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

text: " Combining clusters of magnetic materials with a matrix
of other magnetic materials is very interesting for basic research because new,
possibly technologically applicable magnetic properties or magnetization reversal
processes may be found. Here we report on different arrays combining iron and
nickel, for example, by surrounding circular nanodots of one material with a matrix
of the other or by combining iron and nickel nanodots in air. Micromagnetic simulations
were performed using the OOMMF (Object Oriented MicroMagnetic Framework). Our
results show that magnetization reversal processes are strongly influenced by
neighboring nanodots and the magnetic matrix by which the nanodots are surrounded,
respectively, which becomes macroscopically visible by several steps along the
slopes of the hysteresis loops. Such material combinations allow for preparing
quaternary memory systems, and are thus highly relevant for applications in data
storage and processing.\r\n "
