Resumen: Magnetometry, neutron diffraction experiments, and high-resolution transmission electron microscopy (HRTEM) were performed to study the magnetic behavior of CuCr2−SnS2Se2 (0.2≤≤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 ( 3 ) 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 ≤0.4 there is a ferromagnetic long-range order at high temperatures labeled with the 3 irrep mΓ+ 4 of ‾ 3 .1′, while for >0.4 no magnetic signal is observed, indicating that the ferromagnetic behavior is suppressed and replaced with a spin-glass-like state.
