Solid-state materials showing giant caloric effects near room temperature could provide an alternative to cooling devices based on gas cycles. Strong emphasis has so far been dedicated to caloric effects induced by a magnetic field. It is now demonstrated that a small pressure applied to the compound Ni—Mn–In gives rise to a giant caloric response.
