摘要

The aim of this work is to understand the properties of manganites doped with nickel ions. The influence of different synthesis conditions on the crystal and magnetic structure as well as magnetic properties of the compositions of the La_(1-x)Sr_(x)Mn_(0.65)Ni_(0.35)O_(3) system (0 ≤ x ≤ 0.3) are investigated. It is suggested that antiferromagnetism in the composition with x = 0.3 is associated with strong negative exchange interactions Ni~(2+)?O?Ni~(2+) and Mn~(4+)?O?Mn~(4+) and the ions disordering.
