PURPOSE:To improve the fluidity and the orientational property when a molding operation is conducted by a method wherein the rare-earth metal containing at least a kind of Nd and Pr, iron, boron and zirconium is formed into a specific thickness using a method of quenching in liquid. CONSTITUTION:The title permanent magnet of 100mum in thickness is formed by an alloy consisting of rare-earth metal (of a rare-earth element containing Y, at least a kind selected from Nd and Pr is included), iron, boron, zirconium and other impurities which is inevitable for the manufacture of the permanent magnet using a liquid quenching method. Also, a part of iron may be replaced with the transition metal group such as cobalt, copper and the like. Moreover, the above-mentioned magnet is pulverized into 100mum or smaller, and it is molded after mixing with resin. |
