This letter reports the control of the c -axis orientation and the magnetic properties of L 10 FePd in the well-annealed FePd/Fe thin films Fe (20 nm) /FePd (10 nm) /Fe (5 nm) / SiO2 -substrate and Fe (20 nm) /FePd (5 nm) /Fe (5 nm) / SiO2 -substrate, with the compositions of dual phase region in phase equilibrium. After annealing at 550 °C for 24 h, the c -axis of L10 FePd is controlled to be oriented in the normal direction in the soft Fe matrix. These thin films exhibit the exchange-coupling of hard FePd with soft Fe, and a characteristic spring-magnet behavior showed up reversibly as a significant jump from positive to negative in the magnetization reversal.
