Abstract
A magnetic pole or magnetic shielding film is constructed of a soft magnetic thin film that has a composition represented by formula (Fe.sub.1-x M.sub.x).sub.1-y N.sub.y wherein M is at least one element selected from the group consisting of magnesium, calcium, yttrium, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, and boron, and an atomic ratio x is 0.01.ltoreq.x.ltoreq.0.1 and an atomic ratio y is 0.01.ltoreq.y.ltoreq.0.1. This soft magnetic thin film has a I(200)/I(110) ratio of 0.1 inclusive to 1 exclusive with the proviso that I(200), and I(110) represents an intensity of a diffraction peak for an iron (200) plane, and an iron (110) plane, respectively, as found from an X-ray diffraction pattern, and is substantially free from a diffraction peak for a nitride of the element M, as found from the X-ray diffraction pattern.
