Abstract—

We have synthesized Fe_x(Cu_0.5In_0.5)_{1 – x}Cr₂S₄ 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 Fe_x(Cu_0.5In_0.5)_{1 – x}Cr₂S₄ solid solutions, which provides insight into the nature of the phase transformations involved.

摘要—

我们合成了Fe _x（Cu _0.5 In _0.5）_{1 -x} Cr ₂ S ₄固溶体，并在0.1-45 kOe的静磁场中，在4.2-300 K的温度范围内测量了它们的磁性能。已经确定了合成材料的主要静磁参数：饱和磁化强度，有效磁矩和自旋磁矩，居里和尼尔温度，居里常数以及居里-魏斯常数。如此获得的结果，包括磁团簇的性质和渐近居里温度的成分依赖性，已使用先前报道的Fe _x（Cu _0.5在_0.5）_{1 – x} Cr ₂ S ₄固溶体中，可以深入了解所涉及的相变的性质。
