Effect of Valence Floating on the Magnetic Properties of Ca-Sn Co-Doping Y3−xCaxFe5−xSnxO12(x = 0-0.25)

First-principle calculations were used to simulate the changes in magnetic parameters and interatomic charge density in the crystal structure of yttrium iron garnet (YIG) caused by Ca-Sn co-doping. The simulation results illustrate that Ca and Sn have no spin polarization in the crystal, and the cha...
