Resonance field versus the angle between the external field and the easy axis. The circles represent the resonance fields for CoZr films deposited at a tilted substrate angle of 0° and 60°, respectively. The triangles are theoretical lines obtained by Equation 5. The insets are ESR of the samples with oblique sputtering angle of 0° and 60°.
