Abstract
In this letter we demonstrate thermomagnetic writing in a Co/Pt thin-film layered structure or multilayer: 25×(4.1 Å Co+19 Å Pt). This film exhibits perpendicular magnetic anisotropy, 100% remanence, and a coercive field of 76 kA/m at room temperature. The coercive field is a strong function of temperature and decreases to zero at 250 °C. In this layered film regular domains can be written with low applied fields (below 50 kA/m) and the writing threshold is about 4 mW. Their good magnetic and magneto-optical properties together with their high corrosion resistance make these layers promising candidates for magneto-optical recording.Keywords
