The EPR spectra of Cr 3+ ions in chalcogenide glasses As 2 Se 3 , yM (100 – y ) As 2 Se 3 (M = = Cu, Hg, Pb) and TlAsSe 2 (S 2 ) are observed at X‐, K‐, and Q‐band. It is found that Cr 3+ ions may incorporate into the glass network with surroundings forming intermediate or strong crystalline fields. Considerable fluctuations may occur in the coordinational spheres of the Cr 3+ ions. The phase transition from the ferromagnetic (or ferrimagnetic) state into the antiferromagnetic one is observed for the Cr 3+ spin system in microcrystalline inclusions of CuAsSe glass by EPR and magnetic susceptibility measurements.
