Increased temperature induced chemical ordering and the increase of coercivity. The microstructures of FePtC film showed a two-layer structure with a granular layer above a continuous underlying layer. With increasing sputtering pressure (PAr), the intensity of FePt (001) peak initially increased, and then decreased when PAr ≥ 20 mTorr. At 20 mTorr, Hc value increased to ∼9.5 kOe, and only one magnetic layer was observed with increase of PAr ∼ 50 mTorr. An increase of sputtering power at high pressures will further improve the magnetic isolation of FePt grains. © 2006 IEEE. | Source Title: | IEEE Transactions on Magnetics | URI: | http://scholarbank.nus.edu.sg/handle/10635/86924 | ISSN: | 00189464 | DOI: | 10.1109/TMAG.2010.2042145 |
