Abstract	L1(0)-CoPt was obtained by annealing the CoPt film at 600 degrees C after co-sputtering Co and Pt targets in a magnetron sputtering system. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) results showed a transformation from the face-centered-cubic (FCC) structure to the L1(0) ordered structure during the post-deposition annealing. Thermal stress (S(T)), intrinsic stress (S(i)) and total stress (S(total)) in the films decreased with the increase of the annealing temperature. When the Co atomic composition was 50%, the coercivity of the CoPt film reached to a giant value, around 6300 Oe. The stress was released when the film thickness increased. The relaxed residual stress accounted for the enhancement in the coercivity. Magnetization reversal mechanism of the Co(50)Pt(50) film followed neither the S-W model nor the DWM model.
