Abstract :
This study aims to investigate the Pt doping effects in Ru interlayer to adjust Ru lattice. A DC magnetron sputtering system is used to deposit the films. XRD and TEM are used to evaluate the film orientation and microstructure. Magnetic properties such as perpendicular hysteresis loops and coercivity are tested using a vibrating sample magnetometer. Results show that the highest value for CoCrPt-SiO2 film happens at around 24-28% Pt content, with magnetic anisotropy field of 16.0 kOe.
