A nanogranular thin film consisting of nonmagnetic matrix and ferromagnetic fine particles in nano scale is improved to enhance the thermal stability and the S/N ratio. The ferromagnetic fine particles consist of (FeaCo1-a)1-xPtx, (0.3<=x<=0.7, 0.1<=x<=1), (FeaCo1-a)1-xPdx, (0.3<=x<=0.7, 0.1<=x<=1) or (FeaCo1-a)1-x(PtbPd1-b)x, (0.3<=x<=0.7, 0.1<=x<=1, and 0<b<1).
