Abstract
The Ca2−x Sm x MnO4 (x=0–0.4) compounds were synthesized by a solid–solid method and characterized by XRD at room temperature. The XRD profiles were indexed with a tetragonal structure (I/4mmm space group) for x≤0.3 and orthorhombic one (Pnma space group) for x=0.4. The magnetic measurements were studied as a function of temperature (T=2–300 K) and applied field (μ 0 H=0–10 T). When the temperature decreases, each compound has shown first a ferromagnetic–paramagnetic (FM–PM) transition and then an antiferromagnetic–ferromagnetic (AFM–FM) one. The transition temperatures are found to be Sm-doping dependent. For all compounds, a spin-glass phenomenon is evidenced by FC/ZFC magnetization curves.
