Effective demagnetizing factors (Nxe, Nye) of single-crystal films having cubic or uniaxial anisotropy are derived by new Nxe and Nye equations for the use of Kittel's ferromagnetic resonance formula. Nxe and Nye are obtained by one kind of first derivative (∂G/∂θ). Both first-order and second-order magnetocrystalline anisotropy constants are treated. Six arrangements of films with the static field along the film normal are calculated: (1) perpendicular uniaxial anisotropy, (2) in-plane uniaxial anisotropy, (3) cubic-crystal (001) face, (4) cubic-crystal (011) face, (5) cubic-crystal (111) face, and (6) oblique anisotropy.
