Chemical synthesis of binary Fe-Co oxalate was used for preparation of Fe-Co nanoparticles. X-ray difftaction spectra recorded during temperature treatment in reduction atmosphere show two main stages of transformation: amorphization of the oxalate mixture and formation of Fe-Co nanoparticles. After X-ray diffraction high temperature treatment the nanoparticles with 50 nm mean crystallite were found. Comparison of magnetic properties during and after different type of temperature treatment shows that coercivity and saturation magnetic polarization are sensitive in dependence on sample condition, length of treatment and temperature. Analysis of M¨ossbauer spectra reveal several components which were ascribed different phases during temperature treatments.
