Abstract
Low temperature magnetization studies on polycrystalline EuSe have been performed. The system shows anti-ferromagnetic magnetic ordering with Neel temperature TN ~ 4.6 K and exhibits a field induced meta-magnetic transition, for temperatures below the TN. Arrot plot analysis indicates first order nature for both these magnetic phase transitions. Using the isothermal magnetization measurements, the isothermal magnetic entropy change (−∆SM) is evaluated. The magnetization measurements were done for two different measurement protocols to check the effect of thermo-magnetic history/hysteresis on the magneto caloric properties. Results indicate negligible effect of thermo-magnetic history/hysteresis on magnetic and magneto-caloric properties of the EuSe system.Keywords
