Title:

RARE EARTH METAL MAGNET MATERIAL AND RARE EARTH METAL BONDED MAGNET

Document Type and Number:

Japanese Patent JPH06330252

Kind Code:

A

Abstract:

PURPOSE: To ensure excellent magnetic characteristics in spite of a low rare earth metal content and isotropy.

CONSTITUTION: This rare earth metal bonded magnet consists of, by atom, 2-7% rare earth metals including Y and lanthanides, 1-15% N and the balance Fe and has a two-phase metallic structure consisting of at least a hard magnetic rare earth metal compd. phase and a soft magnetic iron phase. Each of the phases has ≤500nm grain size and coercive force is produced by exchange interaction between the both phases.
