摘要
The structure and magnetic properties of the YFe12-xTix compounds (x=0.85, 1.00, 1.10, 1.20 and 1.30) have been investigated. Both the thermomagnetic analysis and X-ray diffraction patterns show that all compounds studied are almost single phase and crystallize in the ThMn12-type structure. The lattice parameters a, c and unit cell volume V increase monotonously with the increase of Ti content. Curie temperature Tc is almost independent on the Ti content while the spontaneous magnetization M0, the anisotropy field Ba and the anisotropy constant K1 decrease monotonously with the increase of Ti content and the temperature increases from 1.5 K to 293 K.
