摘要:
Abstract The magnetocaloric effect (MCE) of quaternary intermetallic compound ErNiBC has been investigated by magnetization and heat capacity measurements. The compound undergoes a paramagnetic (PM) to ferromagnetic (FM) transition at TC??5 K and the ground state of Er ion forms a Kramer's doublet state. The magnetic transition is found to be second order in nature. The maximum magnetic entropy change (-??SMmax) and adiabatic temperature change (??Tadmax) of ErNiBC are 24.8 J/kg K and 8.6 K, res ...More
