摘要：
A new method for preparing aligned specimens of polycrystalline materials with easy-plane magnetization has been developed in which a powder sample mixed with epoxy is rotated in an applied field. X-ray diffraction and magnetization measurements show that a significant improvement has been achieved in aligning the specimens with this method. For a Y2Co14B specimen prepared by this method, a peak corresponding to the anisotropy field was observed in the second derivative of the room-temperature magnetization curve at a magnetic field of 2.8 T. Computer simulation of the magnetization process shows that there is a peak in the second derivative curve for a well-aligned easy-plane anisotropy sample.
