Abstract
The magnetic and magnetotransport properties of cobaltites La0.5Sr0.5Co1–x Me x O3 (Me = Cr, Ga, Fe) have been studied. The initial compound (x = 0) is a ferromagnet with T C = 247 K and a saturation magnetization close to 2μB per formula unit. It has ben shown that chromium substitution (x = 0.2) decreases the spontaneous magnetization to 0.3μB, while the iron substitution (x = 0.2) does not change the magnetization. The obtained data have been interpreted in a model of positive superexchange interactions between cobalt and iron and negative superexchange interactions between cobalt and chromium.
