|Abstract:||A well-controlled method to fabricate FePt thin films with the (200) texture and longitudinal magnetic anisotropy for high-density magnetic recording media is reported. FePt-Ag nanocomposite thin films with L1 0 ordered FePt grains embedded in an Ag matrix were deposited on the Cr 90Ru 10/ glass by co-sputtering from Ag and FePt targets. The Ag doping suppressed the (001) texture but improved the L1 0 FePt (200) texture. The magnetic easy axis of FePt-Ag thin films changed from perpendicular to longitudinal in direction. In-plane coercivity of the films varied from 0.8 kOe to 6.5 kOe, depending on Ag contents in the films and under-layer thickness. The change from the (001) to (200) texture could be due to the competition of grain-boundary energy and epitaxial-strain energy.|
