摘要

The fractions of clusters and single chromium atoms were calculated by the diluted solution and Heisenberg-Dirac-van-Vleck models for a series of solid solutions containing chromium, strontium, and magnesium in the ratio 5:1:1, respectively. A principal genetic relationship was revealed between La_(1-0.2x)Sr_(0.2x)· Cr_xGa_(1-x)O_(3-δ), La_(1-0.5x)Sr_(0.5x)Cr_xGa_(1-x)O_(3-δ), and La_(1-0.2x)Sr_(0.2x)Cr_xGa_(1-0.2x)Mg_(0.2x)O_(3-δ)systems. Deviations from Curie-Weiss law are observed for the systems with the ratio [Cr]:[Sr]:[Mg]=5:l:l, which point to a noncompensated magnetic moment.
