Heavy-rare-earth-induced structural and magnetic properties in (Sr2-xLnx)FeMoO6 (Ln = Sr, Gd, Tb, Dy , Y and Ho) double perovskite

Effects of organic material on magnetoresistance in electron-doped double perovskite

“…Strong antiferromagnetic correlation exists between the localized magnetic moments (Fe 3+ : 3d 5 ) and the delocalized electron (Mo 5+ : 4d 1 ) in a double-exchange-like type, the magnetic coupling induces a ferrimagnetic state with an ideal saturated magnetization (MS) of 4 per formula unit [2][3][4][5][6][7]. The strength of magnetic coupling in SFMO double perovskite is mainly controlled by the carrier density at the Fermi level, so it indicates that doping electrons in the conduction band is an effective way to enhance TC [8][9][10][11][12][13][14]. This point was confirmed by a substantial enhancement of TC more than 80 K in LaxSr(2-x)FeMoO6 [9]and (Ba0.8Sr0.2)2-xLaxFeMoO6 materials [15].…”
