Abstract
An anisotropic rare-earth bonded magnet having a network boundary phase is provided by imparting melt fluidity accompanied by a slip to a composite granule and compressing and molding the composite granule in a magnetic field together with extensible polymer molecules and a chemical contact. In the bonded magnet, the maximum energy product is 147 kJ/min the thickness of 1 mm, or 127 kJ/min the thickness of 300 μm. This bonded magnet contributes to increase in output and decrease in size and weight of a permanent-magnet motor.
