Interlayer exchange coupling in magnetron-sputtered FePtRuFe trilayers has been investigated. The thickness dependence of in-plane magnetic properties of FePt thin films was investigated and a 12.5-nm -thick FePt film showed both high coercivity and good squareness. The exchange coupling between FePt and Fe layers through a Ru interlayer was obtained with an oscillatory period of about 1 nm. A 0.5 nm Ru layer produced a ferromagnetic coupling between the two magnetic layers and the saturated magnetization is considerably improved through interlayer exchange coupling with Fe.
