| 中文摘要 | The magnetic and magnetocaloric properties of TmNi1-xCuxAl (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) compounds have been investigated. With the substitution of Ni by Cu, the Tm-magnetic moment rotates its direction from basal plane to the c-axis and finally becomes canted antiferromagnetism structure with larger projected moments along the c-axis near T-ord. Furthermore, large reversible magnetocaloric effects have been observed in TmNi1-xCuxAl compounds around T-ord, with no thermal hysteresis and magnetic hysteresis loss. The values of - Delta S-M(max) and refrigerant capacity are greatly improved when the part of Ni was superseded by Cu. In particular, under the magnetic field change of 2 T, a large - Delta S-M(max) of TmNi0.7Cu0.3Al (10.7 J/kg K) is almost twice that of TmNiAl (5.5 J/kg K) and 17.2 J/kg K for TmCuAl around 4 K. The present results indicate that TmNi1-xCuxAl (x >= 0.3) compounds could be considered as good candidate materials for low-temperature and low-field magnetic refrigerant.
