FIG. 2.

Magnetization vs magnetic-field curve recorded at room temperature for film before and after the annealing treatment. The inset is curve of the annealed film in a magnetic field of 5 kOe.

FIG. 3.

(a) -edge EXAFS functions for film before and after the annealing treatment. The reference curves of Co, CoO, and powders, and the -edge function for ZnO film are also shown. (b) Their Fourier transforms (solid line). The empty circles in (b) show the fitting results.
