A magnetic head comprising a magnetic film in at least a part of a magnetic circuit, at least a part of the magnetic film being formed in contact with, or being exposed to, an oxide or oxygen at least in a heating step at 150 DEG C. or higher in a process for preparing the magnetic head is disclosed. An amorphous alloy film for the magnetic film has the following composition formula to give distinguished head characteristics without any oxidation: CoaTbZrcNd where T is at last one of Nb, Ta, W, Mo, V and Cr; N is at least one of Au, Pt and Ag; d>/=1, b>0, b1+b2+2c>/=10, a+d>/=80, -1</=(3c-b1-3b2-5b3-3b4-4d)/(c+b1+b2+b3+b4+d)</=1, and a+b+c+d=100, where b1 is a Nb concentration, b2 is a Ta concentration, b3 is a W concentration, b4 is sum total of Mo, Cr and V concentrations and b=b1+b2+b3+b4.
