"-FeN is a promising candidate for the recording media of high-density magnetic recoding tapes because it was reported that this compound has a giant magnetic moment of 2.9 T larger than pure Fe. It was, however, difficult to synthesize a homogeneous specimen of a single phase. We have succeeded to synthesize the homogeneous and single-phase FeN thin films, and have been investigated the giant magnetic moments using Mssbauer spectroscopy and polarized neutron diffractometry. In this talk, the results of the polarized neutron diffraction measurements are reported.
