Description
Magnetic anisotropy is defined as the magnetization tendency of magnetic material in a particular crystallographic direction. We studied the magnetic anisotropy of pure CoS$_2$ single crystal, besides the effect of crystal structure and low doping concentrations. We used torque magnetometer measurement to determine the crystals' magnetocrystalline anisotropy. To verify the effect of surface morphology on magnetic properties, $\tau$($\theta$) of uncleaved and cleaved pure CoS$_2$ was compared. The angle dependence of torque $\tau$($\theta$) for pure CoS$_2$ was measured in a wide range of temperatures above and below the ferromagnetic order transition $T_\rm c$, under the magnetic field; the angle $\theta$ is the orientation of the applied field for the crystals' c-axis.
