| Abstract Scope |
Soft magnetic amorphous and nanocrystalline nanocomposite materials represent attractive systems for both existing and emerging wide bandgap semiconductor power electronics applications. Tailoring of magnetic properties for a specific application can be achieved through optimization of the permeability of the material by development of induced magnetic anisotropies. Such induced anisotropies, if not carefully controlled, can also yield increased losses which are undesirable and can negatively impact performance in application. In the case of high temperature applications, the thermal stability of induced anisotropy can be the primary limitation for long-term stable operation and can show a dependence upon not only material chemistry and processing conditions, but also the detailed excitation conditions. Here we review current understanding of induced magnetic anisotropies in soft magnetic amorphous and nanocrystalline nanocomposites and we discuss recent insights into mechanistic origin and high temperature stability with an emphasis on high induced anisotropy Co-rich nanocomposite systems. |
