研究了硼对Heusler合金Ni50Mn36.5Sb13.5−xBx（x= 0，0.5，1.0，1.5）中Sb的替代效应。用B替代降低了马氏体和奥氏体相的居里温度。饱和磁化强度Ms随B含量的增加而单调减小。B的掺杂有效地提高了马氏体相变温度。当x=1.0和1.5时，室温下观察到正交四层（4O）马氏体。
The effect of boron substitution for Sb in the Heusler alloys Ni50Mn36.5Sb13.5−xBx(x=0, 0.5, 1.0, 1.5) has been studied. The substitution with B reduces the Curie temperature of both the martensite and austenite phases. The saturation magnetization Msdecreases monotonically with increasing B content. The doping of B increases the martensitic transformation temperature effectively. When x=1.0 and 1.5, an orthorhombic four-layered (4O) martensite is observed at room temperature.
