Abstract
CoPt/Ag and [C/CoPt]n/Ag thin films have been prepared onto the glass substrates by magnetron sputtering. We investigated the evolution of texture and magnetic properties of CoPt/Ag and [C/CoPt]n/Ag films. The results show that C-doping plays an important role in improving (0Â 0Â 1) texture, improving the order parameter S, reducing the intergrain interactions, and making the magnetization reversal mechanism more close to Stoner-Wolfarth rotational mechanism. The growth mechanism of (0Â 0Â 1) texture also seems to be related strongly to the films thickness. Our results show that the highly (0Â 0Â 1)-oriented films with ordered fct phase have a significant potential for the perpendicular media of extremely high-density recording.
