这项工作报告的Heusler化合物Co2FeSi的结构和磁性的调查。X射线衍射和穆斯堡尔谱表明，有序的L21结构。通过X射线磁性圆二色性和磁性测量表明，该化合物是目前Heusler化合物和半金属铁磁体中具有最高磁矩（6μB）和居里温度（1100 K）的材料。
This work reports on structural and magnetic investigations of the Heusler compound Co2FeSi. X-ray diffraction and Mosbauer spectrometry indicate an ordered L21 structure. Magnetic measurements by means of x-ray magnetic circular dichroism and magnetometry revealed that this compound is, currently, the material with the highest magnetic moment (6μB) and Curie temperature (1100K) in the classes of Heusler compounds as well as half-metallic ferromagnets.
