中文摘要 | Magnetic and magnetocaloric properties of binary equiatomic alloys RAl (R = Ho and Er) are investigated in this work. HoAl compound undergoes antiferromagnetic (AFM)-ferromagnetic (FM) transition at T-1 = 13 K, and FM-paramagnetic (PM) transition at the Curie temperature T-C = 20 K, with temperature increasing. ErAl compound exhibits AFM-PM transition at the Neel temperature T-N = 9 K. The maximal values of magnetic entropy change (Delta S-M) are -22.5 J kg (1) K (1) for HoAl and -16.4 J kg (1) K (1) for ErAl for a magnetic field change of 0-5 T. The values of refrigerant capacity (RC) are 379.5 J kg (1) and 259.7 J kg (1) for HoAl and ErAl respectively. The large magnetocaloric effect makes RAl (R = Ho and Er) compounds promising candidates for low-temperature magnetic refrigerants. (C) 2014 Elsevier B. V. All rights reserved. |
