在对Heusler合金的全面检查过程中发现，以前被报道为铁磁性的Cu2MnSb合金显示出反铁磁体的一些性质。该合金是在1000℃熔化，650℃均化50小时，然后在水中淬火制备的。样品的成分为Cu2.000Mn0.998Sb1.026±0.00。X射线衍射分析表明，样品中存在类似于Cu2MnAl合金的Heusler结构，其点阵参数为6.097±0.004？，介于5.95？和6.20？之间。对于Cu2MnAl和Cu2MnIn，它们都是铁磁性的。
IN the course of a comprehensive examination of the Heusler alloys it has been found that the alloy Cu2MnSb, previously reported as ferromagnetic1, shows some of the properties of an antiferromagnet. The alloy was prepared by melting at 1,000° C., homogenizing at 650° C. for 50 hr., and quenching in water. The composition of the specimen was Cu2.000Mn0.998Sb1.026± 0.001.X-ray diffraction analysis showed the presence of Heusler structure similar to that of the alloy Cu2MnAl, with a lattice parameter 6.097 ± 0.004 Å., which is intermediate between the values of 5.95 Å., and 6.20 Å. for Cu2MnAl and Cu2MnIn respectively, both of which are ferromagnetic.
