TRANSPARENT MAGNETIC METAL FILM AND MANUFACTURING METHOD OF SAME

摘要

PROBLEM TO BE SOLVED: To provide a transparent magnetic metal film that is transparent to light even when it is a metal thin film and a manufacturing method of the same.SOLUTION: A transparent magnetic metal film body 100 includes: a substrate 110; and a transparent magnetic metal film 120. The transparent magnetic metal film 120 contains Fe as a component. The transparent magnetic metal film 120 has optical transmittance of higher than or equal to 50% over a wavelength region of greater than or equal to 400 nm and less than or equal to 1000 nm. The transparent magnetic metal film 120 is a thin film exhibiting ferromagnetism.SELECTED DRAWING: Figure 2
