چکیده انگلیسی
An attempt has been made to probe low temperature magnetic state of the polycrystalline Sm0.5Ca0.5MnO3 compound via magnetization and magnetocaloric studies. In the context of the earlier debatable reports on the above mentioned compound between the existence of glassy magnetic state and small ferromagnetic domains from the 'ac' susceptibility measurements, our experimental observation from magnetocaloric effect study clearly indicates the existence of ferromagnetic droplets along with certain amount of superparamagnetic component at low temperature (< 40â¯K) which begins at Tâ¯â¼â¯100â¯K. In addition to that, the zero field cooled magnetization (even at Hâ¯=â¯0.01â¯T) data do not exhibit the spin freezing nature at the low temperature which is almost a generic tendency of glassy magnetic state. Our study also highlights the competence of magnetocaloric effect as a tool to distinguish between different magnetic states of a compound.
