本文报道了在310 K附近发生马氏体相变的多晶Ni 45.2Mn 36.7In 13 Co 5.1合金的磁形状记忆效应。磁场的应用使转变温度降低了6.7 K/T。起源于磁致马氏体-奥氏体相变，在310 K的0.25%的大磁应变观察织构多晶Ni 45.2 Mn 36.7 In 13 Co 5.1样品。温度，各向异性，和循环磁应变的影响进行了讨论。(C)2009年美国物理学会。[doi：10.1063/1.3273853]
This letter reports the magnetic shape memory effect in a polycrystalline Ni45.2Mn36.7In13Co5.1 alloy having the martensitic transformation around 310 K. An application of magnetic field shifts the transformation to lower temperatures by 6.7 K/T. Originating from the magnetically induced martensite-austenite transformation, a large magnetostrain of 0.25% at 310 K was observed in a textured polycrystalline Ni45.2Mn36.7In13Co5.1 sample. Temperature, anisotropy, and cycling effects on the magnetostrain are discussed. (C) 2009 American Institute of Physics. [doi: 10.1063/1.3273853]
