Abstract
FeNi L10 (tetrataenite) phase has great perspectives for hard magnetic materials production. In this paper it was synthesized in chemically co-precipitated FeNi nanopowder by means of thermal treating included cycling of oxidation and reduction processes at 320 {\deg}C. The presence of FeNi L10 phase in the samples was confirmed by magnetic measurements and DSC analysis.
