Abstract

The magnetocaloric effect was examined for ErCo₂, which shows a first-order magnetic transition from a ferrimagnetic to paramagnetic state at 32 K. A large magnetic entropy change was caused by a magnetic field. The corresponding entropy change ΔS and the adiabatic temperature change ΔT_ad are 12 J/K mol and 13 K, respectively in a change of magnetic field 0-8 T at 32 K. The substitution of 20% Y for Er leads to a reduction of the magnetocaloric properties by 20-30%. The origin of the large magnetocaloric effect is also discussed.
