) and Fe11CrC4(s), the Fe of Wyckoff positions of 8d and 4c is substituted by Cr. The local magnetic moment of Cr at 8d site is larger than that at 4c site in the doped structure, which is opposite..., Cr(g) possesses a larger magnetic moment with spin-down. On the other hand, the spin polarization of C atoms resulting from the hybridization with the neighboring metal atoms, the magnetic moment......

The Nd-Fe-B powders were recycled from electronic wastes by the ball... and magnetic moment were increased with the Nd-Fe-B concentration increasing. Furthermore, the electrical current in the solenoid required for the attraction of the magnetic wood composites......
; (2) where M is the net overall magnetic moment; a is the lattice parameter. The cation distribution of the NZTF ferrite thin films is (Zn0.5Fe0.5)[Ni0.5+xTixFe1.5-2x]O4. Due to antiferromagnetic coupling, the net overall magnetic moment is equal to the result of magnetic moment from B sites minus magnetic moment from A sites, M=MB-MA......

sputtering. The influences of Tb doping on the soft magnetic capability and microwave complex permeability were investigated. The results show that the microstructure and soft magnetic parameters change little with a little Tb doping, thus, amorphous microstructure and good soft magnetic performance are still kept, but relaxation in the microwave magnetic spectra is strengthened, and the permeability......
