在优先织构的Mn50Ni40In10带材中评估逆磁热特性和正磁热特性，施加磁场H-平行于带材长度和垂直H-垂直于带材平面（Delta H= 30 kOe）。最大磁熵变、磁滞损失和制冷剂容量不受晶体结构的显着影响。结构转变周围的制冷能力因与变磁场引起的逆马氏体转变相关的大磁滞损耗而大大降低，并且工作温度范围更窄，使得磁转变周围的间隔对于制冷剂循环更加有效（RCstruct=71 J kg(-1)，而 RCeffstruct 接近 60 J kg(-1)，并且 RCmagn= 89-86 J kg(-1)，分别表示 H 平行于和 H 垂直于）。 (c) 2009 年美国物理研究所。 [DOI：10.1063/1.3147875]
Inverse and direct magnetocaloric properties were evaluated in preferentially textured Mn50Ni40In10 ribbons applying the magnetic field H-parallel to along the ribbon length and perpendicular H-perpendicular to to the ribbon plane (Delta H= 30 kOe). Maximum magnetic entropy change, hysteretic losses, and refrigerant capacity were not significantly affected by crystallographic texture. Refrigeration capacity around structural transition is strongly reduced by the large hysteretic losses associated to the metamagnetic field-induced reverse martensitic transformation and narrower working temperature range making the interval around the magnetic transition more efficient for a refrigerant cycle (RCstruct=71 J kg(-1) versus RCeffstruct approximate to 60 J kg(-1), and RCmagn= 89-86 J kg(-1), for H-parallel to and H-perpendicular to, respectively).
