On the Magnetic Anisotropy of Single Crystal of Chromium Telluride

抄録

The anisotropy of a ferromagnetic single crystal of CrTe with NiAs structure was investigated by magnetic torque measurements. From the experiment it was seen that the axis of easy magnetization is [001] and it does not change from room temperature to liq. He temperature. At 0°K the uniaxial anisotropy constant will be about 5×10⁶ erg per cm³. As for the origin of anisotropy, the dipole-dipole energy can account for only about 20 percent of the observed value.
