Neutron diffraction studies of the compounds MnN and FeN

The compounds MnN and FeN were prepared as single phase sample by DC reacti ve sputtering. The crystal structure of MnN is tetragonally distorted NaCl type and that of FEN is ZnS type. Temperature dependence of the neutron dif fraction pattern on MnN was investigated. Analysis of the data shows that t he magnetic structure of MnN consists of ferromagnetically aligned c-planes coupled antiferromagnetically in the c-direction. The magnetic moment of m anganese atom extrapolated to OK was found to be 3.3 mu (B) and lie. in c-p lane. The neutron diffraction measurements of the compound FeN were also ca rried out;. The ZnS type FeN was concluded to be non-magnetic down to 2.2 K .
