(a) The layer structure of the ( CoIr ) 100 − x P x systems and (b) the XRD patterns for SiO8.7, Ni7.1, and B8.7 films. (c) The typical transmission electron microscopy (TEM) image showing the columnar type growth of magnetic layer. (d) and (f) The high resolution imaging of the magnetic layer revealing the degree of c-axis orientation.
