Abstract

PURPOSE: To raise the residual magnetic flux density of a rare earth element.cobalt magnet (R.Co magnet) consisting of one or more kinds of rare earth elements and one or more out of Co, Fe, Mn, etc. without deteriorating the coercive force by mixing powder of the R.Co magnet with powder of permanent magnets such as Cr steel, followed by molding.
CONSTITUTION: Powder of an R.Co magnet consisting of one or more kinds or rare earth elements and one or more out of Co, Fe, Mn, Ni and Cu is mixed with powder of one or more kinds of permanent magnets selected from Cr steel, Co steel, ESD, Vicalloy, Cunife and Mn-Al. The mixed powder is then press molded in a magnetic field and sintered or binded with an org. binder or a low m.p. matal binder.
