<p>An object of the present invention is to provide a magnetic recording medium comprising a magnetic film, which has a high normalized coercive force, suppresses thermal agitation and also has thermally stable magnetic characteristics, an alloy, and a method of producing an alloy and the magnetic recording medium, and a target for forming a magnetic film. The present invention provides a magnetic alloy consisting essentially of cobalt (Co), chromium (Cr), and germanium (Ge), the composition of said magnetic alloy being represented by the general formula: CoxCryGez where x, y and z, which represent the composition ratio, satisfy the relationships: 78 </= x </= 87, 2.5 </= y </= 14.5, 3.5 </= z </= 15, and x + y + z = 100 (provided that x, y, and z represent the composition ratio in terms of atomic %). Furthermore, the present invention may provide a magnetic alloy with a composition represented by the formulas: CoCrGeT (T represents one or more elements of Ta, Si, Nb, B, Ni and Pt) or a composition represented by the formula: CoCrGeT' (T' represents one or more elements of Ta, B, and Pt). <IMAGE></p> |
