INVESTIGATION OF THE SPIN REORIENTATION IN A DYFE10V2 SINGLE-CRYSTAL

The spin reorientation caused by the competition between the contribut ions of iron and rare-earth ions to the magnetic anisotropy of rare-ea rth iron compounds is investigated on a DyFe10V2 single crystal. The m easured field and temperature dependence of the magnetization, the AC- susceptibility and the torque curves reveal the presence of only one s pin reorientation, at T-SR = 145 K. At low temperatures, the angle of the easy direction of magnetization with the c-axis is about 30 degree s. A magnetic anisotropy is found for different directions of fields a pplied in the plane perpendicular to the c-axis for temperatures below as well as above the spin reorientation.
