摘要：

The low-temprature heat capacity and ac and de magnetic properties of (Dy0.5Er0.5)Al-2 have been studied as a function of magnetic fields up to similar to 10 T The magnetocaloric effect in (DY(0.5)ET(0.5))Al-2 is 30% larger than that of the prototype material, GdPd. Magnetic measurements show that there is no measurable magnetic hysteresis above similar to 17 K. These results suggest that (Dy0.5Er0.5)Al-2 would be a significantly better magnetic refrigerant than GdPd.
