Magnetic properties of iron-nitride particles prepared with gas evaporation method

Abstract
Magnetic properties of iron nitride particles prepared with reactive gas evaporation method were investigated. Major products for higher NH3gas pressure region is &'Fe4N and &Fe. For lower pressure region &Fe was produced, which was oxidized to Fe3O4after exposure to air. It is found that particles consist of &'Fe4N and &Fe are more persistent to oxidation comparing to those of &Fe.
