Fine Tuning Magnetic Properties of FePt:C Thin Films By FePt UnderLayers

摘要：

　　Nonepitaxially grown FePt(x)/FePt.:C thin films were synthesized,where FePt(x) (x=2,5,8,11,14 nm) layers were served as underlayers and FePt.:C layer was nanocomposite with thickness of 5 nm.The effect of FePt underlayer on the ordering,orientation and magnetic properties of FePt.:C thin films has been investigated by adjusting FePt underlayer thicknesses from 2 nm to 14 nm.X-ray diffraction (XRD),together with transmission electron microscopy (TEM) confirmed that the desired L10 phase was formed and films were (001) textured with FePt underlayer thickness decreased less 5 nm.For 5 nm FePt.:C nanocomposite thin film with 2 nm FePt underlayer,the coercivity was 8.2 KOe and the correlation length ofFePt:C nanocomposite film was 67 nm.These results reveal that the better orientation and magnetic properties for FePt.:C nanocomposite films can be tuned by decreasing FePt underlayer thickness.
