SYNTHESIS, CRYSTAL STRUCTURE, AND MAGNETIC PROPERTIES OF LANTHANUM-STRONTIUM MANGANITES CONTAINING NICKEL IONS

abstract

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 La1-xSrxMn0.65Ni0.35O3 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 Ni2+-O-Ni2+ and Mn4+-O-Mn4+ and the ions disordering.
