摘要：
Magnetically isotropic, fine grain, RE.sub.2 Fe.sub.4 B phase containing particulate material is hot pressed to full density and bonded to a metal backing layer of desired shape and composition. Additionally, if desired, the fully dense isotropic material can be further deformed in a direction lateral to the press direction so as to strain the particles to align the preferred magnetic axes of the crystal grains therein and thus form a laminate of a magnetically anisotropic magnet layer bonded to a metal backing layer.
