Perpendicular magnetic anisotropy of Fe-Cr-N nanocrystalline films, prepared by reactive sputtering, have been analyzed by vibrating sample magnetometry, magnetic torque, Mossbauer spectroscopy and ferromagnetic resonance (FMR) measurements. The torque measurement shows that the film has a uniaxial anisotropy whose easy axis lies along the normal to the film plane. The Mossbauer spectra at room temperature (RT) and 4.2 K consist of a broad hyperfine sextet of the α-Fe (Cr) phase and a paramagnetic doublet of the γ-(Fe,Cr)_4N_x phase. The broad spectrum is attributable to a distribution of the hyperfine field. The FMR experiment also shows a broad ferromagnetic absorption peak, resulting from the size and orientation distribution of the fine α-Fe (Cr) grains which have the shpae anisotropy.
