Abstract
The magnetic phase transitions and the magnetocaloric effect in the Ising antiferromagnet DySb have been studied. A field-induced sign change of the magnetocaloric effect has been observed which is related to a first-order field-induced metamagnetictransition from the antiferromagnetic to the ferromagnetic states at/below the Néel temperature T N , while the negative field-induced entropy change is found to be associated with the first-order magnetic transition from the paramagnetic to the ferromagnetic states above T N . The large magnetic-entropy change ( − 20.6 J ∕ kg K at 11 K for a field change of 7 T ), together with small hysteresis, suggests that DySb could be a potential material for magnetic refrigeration in the low-temperature range.This publication has 23 references indexed in Scilit:
