PURPOSE:To provide an inexpensive and practical magnetic material by constituting the composition of a permanent magnet material of specific atomic percentages of rare earth elements, Ti, and C and the balance Fe. CONSTITUTION:This permanent magnet material has a composition consisting of, by atom, 1-8% R (where R means one or >=2 kinds among the rare earth elements including Y), 16-32% Ti, 5-21% C, and the balance Fe. As the rare earth elements, one kind among arbitrary elements, such as Nd, Sm, Pr, and Ce, can be used or two or more kinds among them can be properly used in combination. By this method, high magnetic properties can be obtained while minimizing the use of expensive rare earth elements and obviating the necessity of Co unstable in supply. |
