Voltage-controlled magnetic anisotropy (VCMA) in an epitaxially grown Fe/Fe1-x Co x /Pd/MgO system was investigated using spin-wave spectroscopy. The spin-wave resonant frequency linearly depended on the bias-voltage. The resonant-frequency shift increased with the Co fraction in Fe1-x Co x /Pd. We achieved a VCMA of approximately 250 fJ/Vm at the Co/Pd/MgO region.
