Abstract

A giant low-field reversible magnetocaloric effect was reported in ErCr ₂Si ₂ compound at ∼4.5 K, which is just above the boiling point of helium. Under a field change of 2 T, the maximum values of magnetic entropy change and adiabatic temperature change are achieved: 24.1 J kg ^-1 K ^-1 and 8.4 K, respectively. The low-field giant magnetic entropy change, together with the absence of thermal and field hysteresis, makes the ErCr ₂Si ₂ compound an attractive candidate for low temperature magnetic refrigeration.
