A magnetically soft thin-film is prepared either to be of a composition wherein Fe is used as a principal component, and 0.5 to 20 atomic % of Al, 2 to 25 atomic % of at least one of Zr, Hf, Nb, Ta, Mo and W, 0.05 to 5 atomic % of at lease one of Ag and Cu, 0.5 to 25 atomic % of C and 0.2 to 8 atomic % of O are added as additional elements to the principal component, or to be of a composition wherein 0.1 to 5 atomic % of at least one of rare earth elements such as Ce, Sm and Dy is added further to the above-stated composition. These compositions enable the magnetically soft thin-film to have excellent properties as desired for a magnetic head.
