摘要： An exchange-spring magnet is prepared using a magnet alloy containing Ta and C in addition to Nd, Fe and B. This exchange-spring magnet uses the magnet alloy prepared by a liquid quenching method or a mechanical alloying method. Further, by subjecting the magnetic alloy having a part set in an amorphous state to heat treatment, an exchange-spring magnet exhibits good properties regarding magnetic flux density and coercive force.
