Abstract
We have investigated the magnetic and magnetocaloric properties of DyVO4 by magnetization and heat capacity measurements. χ ( T ) shows antiferromagnetic to paramagnetic transition at T N Dy ~ 3.5 K . The compound undergoes a metamagnetic transition and exhibits a huge entropy change. The maximum values of magnetic entropy change ( Δ S M ) , adiabatic temperature change ( Δ T ad ) and refrigerant capacity (RC) reach 26 J kg−1 K−1, 17 K, and 526 J kg−1, respectively for a field change of 0–8 T. Moreover, the material is highly insulating and exhibits no thermal and field hysteresis, satisfying the necessary conditions for a good magnetic refrigerant material.
