PURPOSE:To obtain a magnet having a stabilized tetragonal compound, a high Curie point and high degree of magnetic characteristics by a method wherein the Ti and M of the prescribed quantity is added to an R-Fe compound. CONSTITUTION:A permanent magnet is obtained using a five-component alloy shown by a formula RxTiyMzFeaCob. The R in the formula indicates one or more kinds of the rare earth elements containing Y, M indicates Zr or Hf, and the range of their composition in weight percentage is x=12-30%, y=1-8%, z=0.1-8%, a=55-80%, and b=34% or below. This five-component compound has a tetragonal structure, its indexing is possible, and the temperature variation of magnetization is approximately of a single phase. The tetragonal compound can be stabilized by introduction of Ti and Zr. |
