--- _id: '1601' abstract: - lang: eng text: " Combining soft and hard magnetic materials is not only of technological importance in diverse spintronics elements, but also of high interest in basic research. Here, we report on different arrays combining iron and nickel, e.g., by embedding circular nanodots of one material in a matrix of the other. Micromagnetic simulations were performed using OOMMF. Our results show that magnetization reversal processes are strongly influenced by neighboring nanodots and the magnetic matrix in which the nanodots are embedded, respectively, which becomes macroscopically visible by several steps along the slopes of the hysteresis loops. Such material combinations allow for preparing quaternary memories and are thus highly relevant for applications in data storage and processing.\r\n \ " article_number: '80' article_type: original author: - first_name: Devika full_name: Sudsom, Devika last_name: Sudsom - 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/105572105 citation: alphadin: 'Sudsom, Devika ; Ehrmann, Andrea: Micromagnetic Simulations of Magnetic Particles Embedded in Magnetic or Non-Magnetic Matrices.
