Summary

Erbium-nickel specific heat in 0, 1, 3, and 4.3 T magnetic fields was measured. The specific heat curves for 0 and 1 T have a single peak due to magnetic phase transition, but those for 3 and 4.3 T have no peak. Erbium-nickel specific heat decreases with increasing magnetic field around its ordering temperature, but increases in the higher-temperature region. Using the measured specific heat data, regenerator efficiency and cooling power were calculated to estimate the specific heat reduction influence due to a magnetic field on the erbium-nickel regenerator performance.
