Magnetic and structural properties of the chromium-based Mn1 xCdxCr2S4 thiospinel

Artículo de publicación ISIThe (Mn1−xCdx)Cr2S4 phases (0≤x≤0.6) have been synthesized from the corresponding elements at
1123 K. These sampleswere characterized by powder X-ray diffraction (XRD) and magnetic susceptibility.
The(Mn1−xCdx)Cr2S4 compounds crystallize in the space group Fd-3m with cell parameters a = 10.101(6) Å,
10.139(3) Å, 10.165(2) Å, and 10.192(1)Å for x = 0, 0.2, 0.4 and 0.6, respectively. An overall ferrimagnetic
behavior is observed for all samples. The ferromagnetic component increases rapidly when manganese is
substituted by non-magnetic cadmium, as shownby ZFC/FC measurements. At the same time, the value of
the magnetizationM50 at 50 kOe, deduced fromM(H) loops, also increases with increasing cadmium content
because the antiferromagnetic alignment between chromium and manganese spins is progressively
lost, leading toward well aligned moments pointing into the same direction. These results are explained
by a rearrangement of the chromium spins when Mn located at the tetrahedral sites, is substituted
by Cd
