Abstract
CuCr1.5 + x Sb0.5–x S0.5Se3.5 (x = 0–0.5) mixed chromium chalcogenide spinels have been synthesized for the first time. Their magnetic properties have been studied, their magnetic transformations have been identified, and the magnetic phase diagram of the solid solution system has been mapped out. The CuCr2S0.5Se3.5-based ferromagnetic materials have the largest phase field in the system (0.23 ≤ x<0.5). With decreasing temperature, the materials undergo a reentrant transition to a spin glass state. In the composition range 0.12 ≤ x ≤ 0.23, the transition to a spin glass state occurs from the paramagnetic region. The antiferromagnetic materials have the smallest phase field (0 ≤ x ≤ 0.12).
