概要

• 論文の詳細を見る

• Large magnetic entropy change (7.5 J/kg・K) was discovered in Nd_<0.5>Sr_<0.5>MnO_3 under a low magnetic field of 10 kOe at charge-ordered state transition temperature (183 K). It exceeds the magnetic entropy change in Gd by a factor of 2.4 at phase transition temperature under same magnetic field. The physical mechanism is related to the field-induced first-order magnetic, electron and structural transition (from antiferromagnetic charge-ordered state to ferromagnetic charge-disordered state) .
