Abstract

Magnetometry, neutron diffraction experiments, and high-resolution transmission electron microscopy (HRTEM) were performed to study the magnetic behavior of CuCr2-xSnxS2Se2 (0.2?x?1.0) solid solutions and experimentally determine the appropriate magnetic structure for these systems. For all samples, the main phase with normal spinel-Type structure (Fd3¯m) was refined. For low Sn concentration a minority monoclinic phase appears also corroborated with HRTEM analyses. Together with the results from magnetization experiments, neutron diffraction measurements allowed to establish that for samples with x?0.4 there is a ferromagnetic long-range order at high temperatures labeled with the 3d irrep m?4+ of Fd3¯m.1?, while for x>0.4 no magnetic signal is observed, indicating that the ferromagnetic behavior is suppressed and replaced with a spin-glass-like state. © 2024 American Physical Society.
