Giant reversible rotating cryomagnetocaloric effect in KEr(MoO4)(2) induced by a crystal-field anisotropy
Original language description
Magnetocaloric properties of KEr(MoO4)(2) single crystals were investigated using magnetization and specific heat measurements in the magnetic field applied along the easy and hard axis. Large conventional magnetocaloric effect was found around 10 K (-Delta S-max = 14 J/kg K for 5 T) in the field applied along the easy axis. What is more, a huge magnetic anisotropy in the ab plane leads to a large anisotropy of magnetocaloric effect, -Delta S-R,S-max = 10 and 13 J/kg K obtained by a simple rotating of the single crystal within the ab plane in the constant magnetic field 2 and 5 T, respectively. Large Delta S-R values with no hysteresis losses and rather wide working temperature spans imply that KEr(MoO4)(2) may serve as a promising candidate for the implementation of a compact rotary magnetic Cryorefrigerator.
