| 中文摘要 | Structural and magnetic properties, especially the magnetocrystalline anisotropy of DyFe12-xNbx compounds with x = 0.55-0.85, have been investigated. The easy magnetization directions at room temperature for all the compounds are along the c-axis. With decreasing temperature the magnetocrystalline anisotropy changes from easy axis to easy cone at T-sr2, then to easy plane at T-sr1. A spin phase diagram has been constructed for DyFe12-xNbx. The change of magnetocrystalline anisotropy was further investigated by the angular dependence of magnetization with respect to the magnetic field at various temperatures. The temperature dependence of the cone angle was determined for DyFe11.3Nb0.7. It is noteworthy that with increasing Nb content both T-sr1 and T-sr2 decrease monotonically while the Curie temperature is almost independent of Nb content. The cone angle increases monotonically with decreasing temperature from T-sr2 and discontinuously comes up to 90 degrees at T-srl. The temperature dependence of the cone angle can be quite well defined in terms of crystal field theory. In addition, an obvious magnetohistory effect was observed for all compounds at low temperature. The critical field of magnetohistory was found to be smaller than 0.5 T for DyF11.3Nb0.7. |
