In-plane and out-of-plane XRD patterns of (a) MgO sub./Rh (20 nm)/(Fe0.5Co0.5)80V20 (t nm)/SiO2 (5 nm). (b) t dependence of c/a of MgO sub./Rh (20 nm)/Fe (t nm)/SiO2 (5 nm), MgO sub./Rh (20 nm)/Fe50Co50 (t nm)/SiO2 (5 nm), and MgO sub./Rh (20 nm)/(Fe0.5Co0.5)80V20 (t nm)/SiO2 (5 nm). The inset shows a top view of the crystal orientation relationship between the Rh underlayer and the Fe, FeCo, and FeCoV films.
