PROBLEM TO BE SOLVED : To provide : a material for a rare earth magnet which can be preferably used as a raw material of a rare earth magnet, and can contribute to the increase in the rare earth magnet productivity; a method for manufacturing such a material for a rare earth magnet; a laminate magnet, a bond magnet, a compressed magnet, and a sintered magnet which are superior in magnetic property as well as productivity; a method for manufacturing such a bond magnet; and a method for manufacturing such a compressed magnet.
SOLUTION : A material 1 for a rare earth magnet has the following features. (1) The material 1 for a rare earth magnet is composed of a thin plate made of a rare earth-iron alloy including a rare earth element and an iron group element. (2) Supposing that the thickness of the thin plate is represented by t, the length of the thin plate is represented by L, and the aspect ratio is defined as L/t, the aspect ratio L/t is 1.5 or larger. (3) Supposing that the maximum peak intensity of X-ray diffraction of crystal of the rare earth-iron alloy on a surface 1f of the thin plate is represented by Imax, the peak intensity of X-ray diffraction concerning a c-axis of the crystal lattice of the rare earth-iron alloy is represented by Ic, and the peak intensity ratio is defined as Ic/Imax, the peak intensity ratio Ic/Imax is 0.83 or larger.
