Abstract

Specific heat of magnetic material ErNi_0.9Co_0.1 was measured in a temperature interval between 1.5 and 35 K in magnetic fields up to 5 T. This material exhibited a large specific heat suitable for a cryogenic regenerator. The Curie temperature was 6.2 K, which is lower than that of ErNi, 10.5 K. The Gifford-McMahon cycle with an ErNi_0.9Co_0.1 regenerator was numerically simulated and the results were compared to those for ErNi. The cooling power obtained with ErNi_0.9Co_0.1 was 1.4 times higher than with ErNi in a zero magnetic field. When a constant magnetic field of 1.0 T was applied to the ErNi_0.9Co_0.1 regenerator, the cooling power was 1.2 times larger than in a zero magnetic field.
