摘要：

The low-temperature magnetic behaviour of CoxZn1-xRh2O4 (0 ≤ x ≤ 1), polycrystalline solid solutions with the spinel structure, has been studied. Susceptibility measurements showed that an antiferromagnetic order is present in samples with x ≥ 0.50. Magnetization measurements at T = 4.2 K revealed a critical concentration, xc = 0.42 ± 0.02, for a long-range magnetic order. © 1979.
