--- _id: '2284' abstract: - lang: eng text: Improved magnetic memory systems belong to the main research topics in spintronics. Here we show micromagnetic simulations used to analyze the energy density of nano-scaled iron spheres. Layers of different thickness, partly coated with iron oxide, were tested in terms of spatial uniformity of the physical system energy. For a single non-coated or iron-oxide coated droplet, the spatial distribution of the total energy is not uniform and depends on the nano-droplet size. Additionally, for systems consisting of four objects, the relation between relative distance and the resultant magnetization distribution was analyzed. The mutual relation between droplet size and the underlying magnetization distribution as well as the character of local energy extrema was investigated. The size changes for the four-droplet system were compared with the single object behavior to obtain a criterion for the minimum distance between spheres to behave as a single object. The calculations revealed that the oxidized spheres could be placed closer to each other in comparison to the non-coated system. For the proposed oxide coated system, the increase of this maximum packing density is equal to about 12%, as compared to the non-coated system. article_number: '169805' article_type: original author: - first_name: Pawel full_name: Steblinski, Pawel last_name: Steblinski - first_name: Tomasz full_name: Blachowicz, Tomasz last_name: Blachowicz - first_name: Andrea full_name: Ehrmann, Andrea id: '223776' last_name: Ehrmann orcid: 0000-0003-0695-3905 citation: alphadin: 'Steblinski, Pawel ; Blachowicz, Tomasz ; Ehrmann, Andrea: Analysis of the energy distribution of iron nano-spheres for bit-patterned media.

Domain walls in bent nanofibers can nucleate, e.g., due to rotating local magnetic fields. Their propagation through bent nanofibers, however, depends on the bending direction in correlation to the rotational orientation of the magnetic field, making such nanofibers suitable for semi-deterministic logic operations. Here we report on domain wall nucleation, propagation and annihilation in bent nanowire networks with multiple data inputs and outputs. Our results show the influence of the bending radii on domain wall nucleation and propagation, leading to suggestions for possible realization of multi-level systems for logic operations. article_number: '168925' article_type: original author: - first_name: T. full_name: Blachowicz, T. last_name: Blachowicz - first_name: P. full_name: Steblinski, P. last_name: Steblinski - first_name: J. full_name: Grzybowski, J. last_name: Grzybowski - first_name: Andrea full_name: Ehrmann, Andrea id: '223776' last_name: Ehrmann orcid: 0000-0003-0695-3905 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0003-0695-3905/work/105572372 citation: alphadin: 'Blachowicz, T. ; Steblinski, P. ; Grzybowski, J. ; Ehrmann, Andrea: Domain wall nucleation, propagation and annihilation in coupled bent ferromagnetic nanofibers with rotating local input fields.

In purely ferromagnetic samples, such effects can occur due to undetected minor loops or thermal effects. While the exchange bias is long established in hard-disk read/write heads and diverse spintronics applications, minor loops are sometimes used for the calculation of first order reversal curves (FORCs). Reports about their technological relevance, however, are scarce. Here we report on micromagnetic simulations of a nanoparticle with areas of varying height, consisting of tessellations of a defined area, in which the shape anisotropy in narrow higher lines opposes magnetization reversal stronger than in the larger, lower areas between, thus interacting similar to hard/soft magnetic materials although consisting of the same material and thus having identical magneto-crystalline anisotropy. After saturating this nanostructure by a strong magnetic field pulse, distinctly asymmetric, horizontally shifted hysteresis loops can be recognized, especially in the transverse magnetization component. We show the influence of the external magnetic field orientation on this asymmetry. article_number: '168929' article_type: original author: - first_name: Andrea full_name: Ehrmann, Andrea id: '223776' last_name: Ehrmann orcid: 0000-0003-0695-3905 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0003-0695-3905/work/105572395 - first_name: T. full_name: Blachowicz, T. last_name: Blachowicz citation: alphadin: 'Ehrmann, Andrea ; Blachowicz, T.: Magnetization reversal asymmetry in a structured ferromagnetic nanoparticle with varying shape anisotropy.

Nano-rings, with an open aperture in the middle, regularly show flux-closed vortex states without a vortex core, again reducing stray fields. Here we theoretically investigate “Pac-Man” shaped iron nanostructures with varying aperture, i.e. structures ranging from a thin ring to a solid cylinder with a triangular cut. Our results show that in most cases, a vortex-like state without vortex core along the whole nanostructure occurs during magnetization reversal. Depending on the angle of the external magnetic field and the nanostructure thickness, different magnetization reversal processes have been found, including domain wall nucleation and propagation as well as small vortex states with cores. The occurrence of such special magnetic states can be attributed to the interaction of the shape anisotropy with the relatively high magneto-crystalline anisotropy of iron. Our simulations reveal the possibilities to use such structures for data storage applications as well as their importance in basic research, enabling formation of asymmetric magnetic structures beyond common onion and symmetric vortex states. article_number: '168205' article_type: original author: - first_name: Fatima-Zohra full_name: Bachar, Fatima-Zohra last_name: Bachar - first_name: Christian full_name: Schröder, Christian id: '35809' last_name: Schröder orcid: 0000-0002-6391-6548 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0002-6391-6548/work/96660667 - first_name: Andrea full_name: Ehrmann, Andrea id: '223776' last_name: Ehrmann orcid: 0000-0003-0695-3905 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0003-0695-3905/work/96660668 citation: alphadin: 'Bachar, Fatima-Zohra ; Schröder, Christian ; Ehrmann, Andrea: Magnetization reversal in Pac-Man shaped Fe nanostructures with varying aperture.

While the influence of bending radii on the magnetization reversal in such nanofibers was already discussed in the literature, the often occurring beads along the fibers have not yet been investigated in detail. It can be assumed that such beads will support domain wall formation due to a reduction of the relative impact of the shape anisotropy, in this way influencing magnetization reversal along the fiber. Here, we simulate magnetization reversal processes in iron, nickel, cobalt and magnetite fibers with a bead in the middle, produced in three typical dimensions gained by electrospinning. In most cases a vortex state occurs during magnetization reversal, independent from the material and the dimensions. For some angular orientations of the external magnetic field, double-vortex or meander states are visible, usually also followed by vortex states. These simulations underline the strong and highly reliable impact of beads along electrospun fibers, making these structures useful for data storage, transport and other applications. article_number: '167855' article_type: original author: - first_name: Fedi full_name: Amini, Fedi last_name: Amini - first_name: Tomasz full_name: Blachowicz, Tomasz last_name: Blachowicz - first_name: Andrea full_name: Ehrmann, Andrea id: '223776' last_name: Ehrmann orcid: 0000-0003-0695-3905 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0003-0695-3905/work/105571785 citation: alphadin: 'Amini, Fedi ; Blachowicz, Tomasz ; Ehrmann, Andrea: Systematic study of magnetization reversal in beaded fibers from different magnetic materials.
