Optical and magneto-optical properties of thin films for high density information recording

Optical and magneto-optical properties of thin films for high density information recording

It was found that optical and magneto-optical (MO) properties of thin film materials have potential application for blue laser recording. For this purpose, we have used a combination of ellipsometric and polar MO Kerr effect measurements. The optical and magneto-optical properties of Mn(Sb₁-xBix) an...
