<p>A magneto-optical layer sensitive to a light with a short wavelength such as 400 to 550 nm and having a perpendicular magnetization can be deposited on a substrate at a room temperature. The magneto-optical layer is of a tertiary alloy having a composition CoaPtbRuc where 20 </= a </= 70, 10 </= b </= 70, 10 </= c </= 60 and a + b + c = 100 or CodPteRef where d </= 80, 5 </= e, 5 </= f, 40 </= 4d - 5f and d + e + f = 100, and has an easy magnetization axis perpendicular to the main surface of the layer. The magneto-optical layer may be a quaternary alloy CoPtRuRe hat is a certain combination of the above two tertiary alloys. <IMAGE></p> |
