Field Dependence of the Specific Heat of Single-Crystalline {{ZrZn2}}

We present measurements of the specific heat C of a single crystal of ZrZn2 in the range 2\textendash{}30K, at magnetic field B up to 14T. For B=0 and low temperature the specific heat varies as C$\approx\gamma$T+$\beta$T3, where $\gamma\approx$45mJ/molK2 and $\beta$ corresponds to a Debye temperature $\Theta$D$\approx$340K. Magnetic field reduces $\gamma$ by up to 30% at 14T. The variation of $\gamma$ 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.     «
