Application of Nanotechnology in Magnetic Materials

Because of its special structure, nanocrystalline soft magnetic materials have very small magnetic anisotropy, magnetostriction tends to zero, and their resistivity is higher than that of crystalline soft magnetic alloys, but slightly lower than that of amorphous alloys, with high magnetic flux density. , High magnetic permeability and low iron loss comprehensive performance. Nanocrystalline soft magnetic materials were discovered in 1988 by Hitachi, Japan's Gizekken and colleagues, who annealed Fe-Si-B amorphous alloy strips containing Cu and Nb.
