PARAMAGNETIC PROPERTIES OF Cox(Cu0.5Ga0.5)1–xCr2S4 SOLID SOLUTIONS

Abstract

The magnetic properties of Cox(Cu0.5Ga0.5)1–xCr2S4 solid solutions were measured at 5–300 K in constant magnetic fi elds of 0.1 and 45 kOe. Key magnetostatic properties of the analysed samples were determined. These properties include: saturation magnetization, spin and effective magnetic moments, the Curie temperature, the Neel temperature, the spin freezing temperature, the Curie constant, and the Curie–Weiss constant.A corresponding magnetic diagram was made to enhance the analysis of the obtained data. The diagram demonstrates phase transitions occurring within the Cox(Cu0.5Ga0.5)1–xCr2S4 system and their temperature intervals. The diagram provides an overview of the magnetic transitions, enabling us to use this data for the discussion of the results and explain the properties being studied.
