Abstract
Magnetic susceptibility χ measurements in the range from 2 to 300 K were carried out on samples of the Cu2FeSnSe4 and Cu2MnSnSe4 compounds. It was found that Cu2FeSnSe4 was antiferromagnetic showing ideal Curie–Weiss behavior with a Néel temperature TN of about 19 K and Curie–Weiss temperature θ=−200 K, while for Cu2MnSnSe4 the behavior was spin-glass with a freezing temperature Tf of about 22 K and Curie–Weiss temperature θ=−25 K. The spin-glass order parameter q(T), determined from the susceptibility data, was found to be in agreement with the prediction of conventional spin-glass theory.
