Title: Inductive magnetization of low-temperature ordered L1{sub 0}-FePt with CoAg underlayer

Abstract

The feasibility of controlling film microstructure and nanocomposition of FePt film with various compositions of the CoAg underlayer by ion beam sputtering accompanied by an external magnetic field was performed. The characteristic of phase separation of the CoAg underlayer was employed to induce an inductive magnetism region which reduced the annealing temperature acquired for L1{sub 0}-FePt. The segregation of Co atoms could influence the corresponding magnetic properties of FePt. After annealing at 400 degree sign C, the FePt/CoAg films deposited under the magnetic field showed a larger coercivity (H{sub c}=5 kOe) than that of the film deposited without a magnetic field (H{sub c}=0.4 kOe)
