The inverse magnetocaloric effect associated with the martensitic transition in the Ni45.4Mn41.5In13.1 Heusler alloy is reported. A large positive magnetic entropy change of 8J∕kgK under a low magnetic field of 10kOe is found near the martensitic transition temperature. This change originates from the first-order transition from a low-temperature weak-magnetic martensitic phase to a high-temperature ferromagnetic austenitic phase. The large low-field magnetic entropy change indicates a great potential of Ni–Mn–In alloys as working materials for magnetic refrigeration in a wide temperature range.

Our results provide the first evidence that edaravone can protect H2O2-induced cell injury in HT22 neurons via its antioxidant action. These findings suggest that edaravone may be useful in the treatment of neurodegenerative disorders in which oxidative stress has been principally implicated.
