Abstract

Magnetic (Fe1−xCox)59Pt41 alloy thin films have been sputter-deposited on Ti coated Si substrates. The surface morphologies of (Fe1−xCox)59Pt41 (x=0,0.2,0.4,0.8) films changed with increasing Co content. The morphology variation was also correlated with phase transformation. An abnormal enhancement of ordered phase (L10) has been identified at x=0.2, as characterized by X-ray diffraction. Further increase of the Co content suppressed the disorder/order transformation. The abnormal enhancement of ordered phase also correlated to the morphologies of these alloy films. The formation of the order phase (at x=0.2) increased the coercivity of the (Fe0.8Co0.2)59Pt41 thin films. The degree of ordering was also slightly enhanced.
