Description
Summary:This study investigates the magnetic memory and magnetocaloric effects of Sn0.6Cr0.1Ge0.3Te solid solution synthesized by a sealed tube solid-state reaction. Sn0.6Cr0.1Ge0.3Te exhibits ferromagnetic order at Curie temperature (T C = 182 K) and a super spin-glass structure below the blocking temperature. The magnetic memory effect is observed below the spin-glass state, and the change in magnetic entropy is estimated for various magnetic fields. At a magnetic field strength of 60 kOe, the refrigerant capacity, relative cooling power, and the maximum change in magnetic entropy (−ΔS M) values are measured to be 5.5 J/kg, 7.5 J/kg, and 0.107 J/kg-K, respectively. These findings indicate that the Sn0.6Cr0.1Ge0.3Te sample holds great promise as a candidate for applications involving the magnetic memory effect.
