Comparative Study of the Structure and Electromagnetic Characteristics of Manganites Doped with Cation Pairs (Fe,Zn), (Fe,Co), and (Fe,Mg)
摘要
Abstract
The influence of the configuration of ions (Zn2+(3d10), Co2+(3d7), Co3+(3d6), Mg2+(2p6)) replacing manganese in La–Sr manganites on crystal lattice parameters, magnetization, Curie point, semiconductor-metal transition and magnetoresistance has been established. The composition with cobalt in the state of Co3+(3d6) has the highest values of magnetic parameters, and Mg-containing manganite has the lowest values, but it exhibits the maximum magnitude of magnetoresistance.
