摘要

Research highlights: Introducing hydrogen atoms to LaFe _11.5Al_1.5H_x (x=0.12, 0.6 and 1.3) compound can drive the Curie temperature TC to ambient temperature. The magnetic transition is changed from second order to weakly first order with increasing hydrogen content, leading to an increase in the magnetic entropy change ΔSM. The maximal value of ΔSM for x=1.3 is determined to be 6.7 J/kg K at 295 K under a field change of 02 T. Good reversible MCE at low fields makes the hydrides promising room-temperature magnetic refrigerants.
