A trend of increased Electric Power in Aircraft stresses the need of robust, low weight systems with low losses. New hard and soft magnetic materials have made it feasible to work with high speed and high frequency. Applications of new soft magnetic materials and hard magnetic materials like NeFeB magnets have enabled high density power generation systems. A new concept comprising a high speed ...

Both physical and phenomenological models are necessary to obtain good descriptions of coercivity in soft magnetic materials. The former models give insight into the processes involved, while the latter models compute quickly. The differences between modeling soft and hard materials are the parameters sizes and the importance of eddy currents.

Annealing of amorphous precursor alloys, with compositions (Fe,Co!88M7B4Cu1 ~M5Zr, Nb, Hf!, above their primary crystallization temperature results in the nanocrystallization of the ferromagnetic a8-FeCo phase. This work describes results of the characterization of these alloys, including morphological and chemical stability of the a8-FeCo phase, examination of alloy compositions, and developme...

We have computationally studied the properties of higher-order magnetic anisotropy constants in an $L{1}_{0}/A1\text{\ensuremath{-}}\mathrm{FePt}$ core-shell system which is characterized by a strong second-order two-ion Fe-Pt component. show that structure induces unexpected fourth-order constant ${K}_{2}$, magnitude varies nonmonotonically with core-size ratio $R$ reaching peak at $R\ensurema...
