摘要：
Various Fe-Ni alloys are formed by hydrogen reduction at low temperature of a nanometric NiFe2O4 obtained through a wet chemical method. In particular, we have produced bulk quantities of the ordered tetrataenite phase which permitted the measurement of its ferromagnetic transition temperature at 567 degreesC for the first time in a synthetic sample.
