摘要： A fibrous anisotropic permanent magnet is disclosed comprising fibers composed of an alloy comprising at least one of a rare earth metal selected from Nd, Pr, Dy, Ho, Tb, La, and Ce; Fe or Fe and Co; and B, said fibers having a mean diameter of from 50 to 1,000 .mu.m and exhibiting magnetic anisotropy. The fibrous anisotropy permanent magnet is prepared by extruding a molten alloy comprising at least one of Nd, Pr, Dy, Ho, Tb, La, and Ce; Fe or Fe and Co; and B in an oil to quench-solidify the molten alloy into a fibrous form.Since the fibrous magnet exhibits excellent anisotropic magnetic characteristics in the lengthwise direction of the fiber axis in the quench-solidified state, the magnet is particularly useful as a magnetic powder material for an anisotropic bond magnet.
