ScholarBank@NUS Repository. | Abstract: | FePt:Ti O2 (001) thin films were deposited on CrRuMgO underlayers by dc magnetron cosputtering. The effects of Ti O2 content on microstructure and magnetic properties of the epitaxial FePt (001) films were studied. Experimental results showed that even with 20 vol % Ti O2 doping, FePt films could keep a (001) preferred orientation and perpendicular anisotropy. The FePt:Ti O2 (001) film with 5 nm grain size, adjustable coercivity, and reduced exchange coupling was obtained by doping 20 vol % Ti O2 into FePt film, showing great potential as low noise ultrahigh density perpendicular magnetic recording media. © 2008 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/86379 | ISSN: | 00036951 |
