List of Tables

• 7.1. Material parameters of typical Sm(Co,Fe,Cu,Zr)$_z$ permanent magnets [80,93,94,91].
• 7.2. $z$-values for different thickness $t$ of the cell boundary phase around cells with $D=250 \mathrm{nm}$.
• 8.1. Material parameters of FePt (L1$_0$), which have been used for the micromagnetic simulations [102,99].
• 8.2. Coercivity as a function of the easy axis distribution: The first, second, and third number of a triplet in the first column indicates in how many of the six parts of the finite element model the easy axes are parallel to the $z$-, $x$-, and $y$-axis, respectively. Obviously, the coercivity is strongly reduced as compared to the nucleation field of a particle with a single anisotropy axis. However, the mixture of anisotropy axes does not have a significant influence for a particle with 30 nm edge length.
• 9.1. Typical material parameters of permalloy (Ni$_{80}$Fe$_{20}$).
• 9.2. Finite element meshes of different mesh density for a circular nanodot.
• 9.3. Comparison of the energies obtained by the rigid vortex model and numerical FE simulations.
• 10.1. Material parameters for permalloy.
• C.1. Table of material parameters of typical ferromagnets.
