PROBLEM TO BE SOLVED: To improve the corrosion resistance and magnetic characteristic. SOLUTION: This magnet has a compsn. composed of an R2 Fe14 B phase (R is at least one of rare earth elements, including Y) and grain boundary phase existing round that phase. The grain boundary phase contains at least one of Ni, Co, Mn, Cr, Ti, V, Al, Ga, In, Zr, Hf, Ta, Nb, Mo, Si, Re and W 20-90atom.%. |
