Abstract

We present measurements of the specific heat C of a single crystal of ZrZn₂ in the range 2-30 K, at magnetic field B up to 14T. For B = 0 and low temperature the specific heat varies as C ≈ γT + βT³, where γ ≈ 45 mJ/mol K² and β corresponds to a Debye temperature Θ_D ≈ 340 K. Magnetic field reduces γ by up to 30% at 14T. The variation of γ with B is compared with predictions of a self-consistent model of the magnetic equation of state, where phenomenological parameters are taken from the DC magnetization and neutron scattering.
