Abstract
PURPOSE: To manufacture a permanent magnet alloy of high performance at a low cost by allowing about equimolecular amounts of Ni, Fe and Co to be contained in a 1-5 type or 2-17 type intermetallic compound consisting of a rare earth element and a transition metal in place of the transition metal.
CONSTITUTION: About equimolecular amounts of Ni, Fe and Co are allowed to be contained in a 1-5 type or 2-17 type intermetallic compound consisting of a rare earth element and a transition metal and represented by formula RNi2 or R5Fe17 (where R is a rare earth element) in place of the transition metal to obtain a permanent magnet alloy having a composition represented by formula R(NixFeyCo1-x-y)A (where R is Y or Y and one or more among La, Ce, Pr, Nd and Sm which are lanthanide light rare earth elements, 0.02≤x≤0.55, x/y=0.01W25.0, 0.01≤y≤0.65 and 5.0<A<8.5). Thus, the permanent magnet alloy of high performance can be manufactured while reducing the using rate of an expensive element such as Co.
