Morphology of Co–(Mg–F) nanogranular films. (a) Cross-sectional high-resolution transmission electron microscopy (HRTEM) image of the Co26Mg18F56 nanogranular film. (b) Error bar plots of the zero-strain nanogranular diameter (d0) (red plots) and intergranular spacing (s0) (black plots) of Co26Mg18F56, Co38Mg16F46, Co43Mg13F44, and Co47Mg13F40 nanogranular films. d0 and s0 were estimated from the HRTEM image of each film.
