Nitrogen-doped carbon nanomaterials are often produced by the catalytic decomposition of various N-containing organic substrates over nickel-based catalysts. Generally, most such catalysts are ferromagnetic. In the present research, the effect of complete disappearance of ferromagnetic resonance spectra for similar systems during the heat treatment of a NiCu alloy with melamine or g-C3N4 in a closed reaction volume within the temperature range of 450–500 °C was observed for the first time. The X-ray diffraction method showed that the cause of the observed phenomenon is the formation of new products such as nickel nitrides (Ni3N and Ni4N) and a copper-enriched NiCu alloy, which do not possess ferromagnetism at the temperature of registration of their ferromagnetic resonance spectra. The resulting nickel nitrides decompose when the temperature rises above 550 °C to form nickel nanoparticles stable under reaction conditions up to 850 °C and detectable by ferromagnetic resonance spectroscopy.
