Abstract
A method for producing a high magnetic permeability alloy film, wherein an alloy material composed of 1-6 wt % Al, 20-35 wt % Si and the remainder of iron is irradiated with an electron beam in a vacuum deposition apparatus equipped with an electron gun, and the vapor of the alloy material is deposited on a substrate for a predetermined time to form a high magnetic permeability alloy film, comprising further a step of preventing the irregular deposition caused if the concentration of aluminum in the vapor to be deposited increases.
