Paper Abstract

In this paper, we report the fabrication and characterization of two kinds of mediums for magnetically induced superresolution (MSR) and blue wavelength magneto-optical data storage. Both NdGdFeCo/TbFeCo and Pt3Co/TbFeCo exchange coupled double layer structures show good MSR effect. At room temperature (RT), NdGdFeCo and Pt3Co have in-plane magnetization, however, with temperature rising, they become out-of-plane magnetized and copy the bit information of TbFeCo because of strong exchange coupling. This suggests that both of the double layer films are good candidates for MSR/blue wavelength magneto-optical data storage.
