“…Pyrolysis of polycarbosilane polyme by Key et al 43 magnetic semiconductor materials that can maintain the spin orientation of carriers above room temperature for use in the design of magnetoelectric devices is currently under active development. [6][7][8][9][10][11][12][13][14] Moreover, there are other types of ferrite materials, such as composite iron oxides, hexaferrite, dielectric oxides, and superconducting oxides, which also have practical application prospects. [15][16][17][18] In the mixed spinel cubic structure with the space group Fd3m (No.…”
