Abstract

Ferromagnetic resonance at 35 GHz was studied in 200-Å-thick single-crystal α + ′-martensite Fe₉₀N₁₀ (001) films grown on (001) GaAs substrates. From the resonance fields in both (001) basal and (100) vertical planes and the saturation magnetization (4πM) value of 23.0 kG, a large uniaxial anisotropy (K_u) along the [001] axis of 6.36 × 10⁶ erg/cm³, a cubic anisotropy (K₁) of 2.2 × 10⁵ erg/cm³ and the gyromagnetic ratio (g-value) of 2.07 have been determined.
