Title: Permanent magnet
Inventor: KOBAYASHI OSAMU
IPC: H01F1/057
Filed: 1988-06-20
Abstract: PURPOSE:To produce a permanent magnet of high performance and low cost by making base constituents to be a rare earth element, a transition metal and boron of the specific grain diameter and constituent ratio and specifying oxygen concentration. CONSTITUTION:A permanent magnet makes base constituents of a rare earth element R, a transition metal M and boron B. Average crystal grain diameter is 0.3-100mum, a rare earth element 12-14atomic% and oxygen concentration 1000ppm or less in weight percentage. R is a kind or more kinds of elements selected from Y, La, Ce, Pr, Nd, Dy and Tb and M is a kind or more kinds of metals selected from Fe, Co, Ni, Cu, Ag, Au and Zr. When it is grain diameter near to 0.3mum because single-magnetic domain grain diameter of a magnetic phase is 0.3mum, a coercive force mechanism is a pinning type and magnetic adhesion is difficult. When R is 12-14 atomic%, it is very near to an R2Fe14B compound in a composition area and the characteristic very near to a high magnetic characteristic can be obtained. When oxygen concentration 1000ppm or less in weight percentage, oxidation and weather resistance is improved.
