Abstract

The effect of magnetocrystalline anisotropy on the magnetocaloric effect of a single crystal Co₂B alloy is investigated in this study. The alloy is prepared by induction melting under argon atmosphere. Laue and X-ray diffraction are used to determine the lattice parameters, grain growth, and grain orientation of the alloy. The analysis of the temperature and field dependent magnetization curves close to the Curie temperature, performed using the Kouvel-Fisher method, together with the study of the field dependence of the magnetocaloric response, yields information about the details of the transition.
