There is provided a soft magnetic alloy having a composition expressed by formula CoxMzCw, wherein M represents one or more than one of the metal elements including Ti, Zr, Hf, Nb, Ta, Mo, V and W, and x, w and z represent the ratios in terms of atom % of the respective elements in the overall composition satisfying 55</=x</=96, 2</=x</=25, 0.1</=x</=20 and x+z+w=100 and metallurgically consisting of crystalline particles with an average diameter of less than 0.05 mu m. The alloy partially contains carbide(s) of element(s) M in the crystal phase. A magnetic head comprising such a soft magnetic alloy film shows an excellent saturated flux density that can accommodate the requirement of high recording density and other requirements.
