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