| Abstract: | ![]()
A rotation-magnetic-alignment method was used to align fine-powdered (< 20 μm) Er2Fe14B at room temperature while the easy magnetization direction of Er2Fe14B lies in the basal plane. X-ray diffraction was used to check the magnetic alignment. For the first time, the temperature dependence of the anisotropy field of Er2Fe14B was measured in a wide temperature range from about 170 to 530 K. The anisotropy field was determined using the SPD technique in a pulsed-field magnetometer from 170 to 320 K (TSI = 323 K) on a magnetically aligned sample and from 330 to 530 K (TC = 550 K) on a bulk polycrystal. |
