Abstract

We report a magnetically-anisotropic PrCo<subscript>5</subscript> permanent bulk magnet, prepared by a hot deformation method, with crystallographic orientation-dependent magnetic properties. Although the PrCo<subscript>5</subscript> crystals strongly favor the {0001} orientation texture, the crystallographic orientation textures of PrCo<subscript>5</subscript> crystallites differ at various radial locations. From the bulk center to the edge, the c-axis orientation texture decreases from 5.4 MRD to 4.1 MRD, whereas the remanence decreases from 8.93 kGs to 7.58 kGs and the coercivity increases from 4.34 kOe to 6.56 kOe. This paper also reports the alteration of boundary plane orientation textures, resulting from the corresponding energy anisotropy at different locations, and suggests that the development of grain boundaries with lower boundary energies has a significant impact on the magnetic properties with regard to remanence and energy density. The current work therefore proposes an elegant approach to attain desired magnetic properties in PrCo<subscript>5</subscript> magnets by fine-tuning the crystallographic orientation.
