摘要

摘要确定了 La-Sr 锰矿中替代锰的离子（Zn2+(3d10)、Co2+(3d7)、Co3+(3d6)、Mg2+(2p6)）构型对晶格参数、磁化率、居里点、半导体-金属转变和磁阻的影响。Co3+(3d6)状态的钴成分具有最高的磁性参数值，而含镁锰矿的磁性参数值最低，但磁阻最大。

Comparative Study of the Structure and Electromagnetic Characteristics of Manganites Doped with Cation Pairs (Fe,Zn), (Fe,Co), and (Fe,Mg)

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.
