Description	Amorphous silicon carbonitride (a-SiCxNy) thin films deposited on the SiO2 substrates by reactive magnetron sputtering was studied by Raman and electron paramagnetic resonance (EPR) spectroscopy. Raman analysis indicates the presence of C–N, Si–N, C–C bonds in a-SiCxNy films. Three EPR signals were revealed in a-SiCxNy/SiO2. One of them with g=2.0033 was attributed to the carbon-dangling bonds (CDB). Based on the lineshape and linewidth, the EPR signal was attributed to the unpaired electron delocalized over sp2 carbon cluster. With the increase of nitrogen (N) content, the spin density of CDB significantly increases. From the temperature dependence of the linewidth and integral intensity of the CDB EPR signal, it was concluded that the antiferromagnetic ordering occurs in spin system. The antiferromagnetic exchange constant between CDBs was found.
