Structure and magnetic property of the FePt/CrPt bilayer.
In this work we have studied the growth sequence of L10-CrPt antiferromagnetic layer effects on the microstructure and magnetic properties of the FePt/CrPt bilayer. The microstructure characteristics were investigated by means of X-ray diffraction and the magnetic properties were measured at room temperature by using a vibrating sample magnetometer. Structural analysis showed that the low-temperature ordering and the in-plane orientation of the FePt layer with the CrPt underlayer were promoted due to lattice mismatch optimized after annealing at 350 degrees. Meanwhile, magnetic analysis also revealed that the FePt/CrPt bilayer had much larger exchange bias (H(E)) and higher coercivity (Hc) when the CrPt layer was as the underlayer after annealing at 350 degrees.
