چکیده انگلیسی
In this paper, we have investigated the physical properties of SmFe0.5Mn0.5O3 complex perovskite samples, synthesized by means of combustion reaction method. X-ray powder diffraction indicates the formation of single phase perovskite with orthorhombic structure. Low magnetic field measurements show remarkable transition at 234 K related to spin reorientation. The magnetocaloric effect shows two peaks related to magnetic behavior changes, at 18 K and at 234 K. The transition about 234 K presents inverse magnetocaloric effect. The entropy variation from magnetocaloric effect shows power law as function of applied magnetic field with maximum entropy change 5.6 J/kg K with field variation of 70 kOe. Critical exponents extracted from ÎS vs. H presents a remarkable sharp peak near antiferromagnetic to weak ferromagnetic transition temperature.
