摘要
Magnetoresistance (MR) and magnetocaloric effect around martensitic transformation were investigated in a [formula omitted] alloy. The martensitic temperature [formula omitted] locates at [formula omitted]. An external magnetic field can drive [formula omitted] to a lower temperature at a rate of [formula omitted]. Associated with the field-induced metamagnetic behaviors, a large MR takes place. The maximal MR exceeds 80% under a field of 5 T around 235 K. More attractive is that the MR behavior is fully recoverable against magnetic field. We also studied the magnetocaloric effect associated with the martensitic transformation and found a large magnetic entropy change [formula omitted] around 252 K.
