MAGNETIC MATERIAL, MAGNETIC SHAPED OBJECT, AND ROTATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/020617
Kind Code:
A1
Abstract:
An objective of the present invention is to improve such magnetic characteristics of a magnetic material as magnetic moment and magnetic anisotropy. A magnetic material is employed that includes either a binary alloy denoted by a chemical formula of the form R-Fe (where R is either a 4f transition element or yttrium (Y)), or a ternary alloy of the chemical formula R-Fe-T (where R is as per the foregoing description, and T is either a 3d transition element excluding iron (Fe), or else T is aluminum (Al), silicon (Si), gallium (Ga), molybdenum (Mo), niobium (Nb), or tungsten (W), provided that if T is W, then R is either a 4f transition element other than W, or Y). The alloys include either fluorine (F) atoms, nitrogen (N) atoms, hydrogen (H) atoms, or carbon (C) atoms in doping locations in the crystal lattices thereof.
