Abstract—
We have synthesized Fex(Cu0.5In0.5)1 – xCr2S4 solid solutions and measured their magnetic properties in the temperature range 4.2–300 K in a static magnetic field of 0.1 and 45 kOe. The main magnetostatic parameters of the synthesized materials have been determined: saturation magnetization, effective and spin magnetic moments, Curie and Néel temperatures, Curie constants, and Curie–Weiss constants. The results thus obtained, including the properties of magnetic clusters and the composition dependence of the asymptotic Curie temperature, have been interpreted using a previously reported magnetic phase diagram of the Fex(Cu0.5In0.5)1 – xCr2S4 solid solutions, which provides insight into the nature of the phase transformations involved.
