作者研究了许多X2YZ型合金，其中X代表3d过渡金属（或Cu），Y代表第二3d过渡金属或元素La、Th、Zr、Hf、Ta、Nb、W或Mo中的一种，Z代表Al或Ga。结果发现，只有有限数量的这些组合导致立方L21 Heusler型化合物。测定了这些化合物的晶格常数。Heusler L21型相的形成与模型预测进行了比较。对L_（21）型Heusler化合物的磁性和室温克尔旋光的研究表明，铁磁性Heusler合金的克尔旋光与其磁化强度几乎没有相关性。在Co_2YAl和Co_2YGa系列中，Co原子的磁矩和Co与Y组分的电负性差呈线性关系。
The authors have studied a number of alloys of the type X2YZ, where X represents a 3d transition metal (or Cu), Y a second 3d transition metal or one of the elements La, Th, Zr, Hf, Ta, Nb, W or Mo, and Z either Al or Ga. It was found that only a limited number of these combinations leads to the cubic L21Heusler-type compounds. The lattice constants of these compounds were determined. The formation of the Heusler L21-type phase was compared with model predictions. A study to the magnetic properties and the room temperature Kerr rotation of the L21-type Heusler compounds showed that there is hardly any correlation between the Kerr rotation in the ferromagnetic Heusler alloys and the corresponding magnetization. In the Co2YAl and Co2YGa series the moment per Co atom and the electronegativity difference between Co and the Y component showed a linear dependence.
