Grain boundary plane distribution and its potential correlation with magnetic properties in hexagonal RCo5 permanent magnets

Grain boundary plane distributions (GBPDs) are demonstrated to be spatially inhomogeneous in RCo 5 permanent magnets. The potential effect of GBPDs on magnetic properties is proposed from major performance considerations, and approaches to exactly differentiate the boundary population are introduced...

Description
Summary:Grain boundary plane distributions (GBPDs) are demonstrated to be spatially inhomogeneous in RCo 5 permanent magnets. The potential effect of GBPDs on magnetic properties is proposed from major performance considerations, and approaches to exactly differentiate the boundary population are introduced. The crystallographic texture in permanent magnets should cover not only the texture of the crystals, but also the texture between crystals, which is helpful to advance the present understanding of the relationship between textures and properties in permanent magnets. The crystallographic texture in permanent magnets should cover not only texture of crystals, but also texture between crystals.
