Low-temperature growth of perpendicular FePt films

L1/sub 0/ FePt films with high perpendicular coercivity were successfully fabricated by using Cr/sub 65/Mo/sub 15/Mn/sub 20/ underlayers with subsequent forming gas (Ar 95% + H/sub 2/ 5%;) annealing. To adjust the strain energy and the orientation of FePt, Fe and Pt intermediate layers were used. Sa...

Description
Summary:L1/sub 0/ FePt films with high perpendicular coercivity were successfully fabricated by using Cr/sub 65/Mo/sub 15/Mn/sub 20/ underlayers with subsequent forming gas (Ar 95% + H/sub 2/ 5%;) annealing. To adjust the strain energy and the orientation of FePt, Fe and Pt intermediate layers were used. Samples annealed at 275/spl deg/C with thin Pt layers (
