Abstract

Magnetic susceptibility of dilute solid solutions of lanthanum chromate in lanthanum gallate was studied. The calculated antiferromagnetic exchange parameter and distribution of chromium atoms over the diamagnetic matrix gave evidence for enhanced chromium aggregation and weakened magnetic exchange in lanthanum gallate compared to lanthanum aluminate.
