Abstract :
The influence of γ-ray irradiation on the phase transition temperature in (NH2(C2H5)2) 2CuCl4 crystals was investigated. It has been ascertained that irradiation at room temperature leads to increase of transition temperature T1. Contrary to this, irradiation just below T1 is followed by decreasing of transition temperature. Observed effects are connected with breaking of H-bonds and with corresponding change of Cu2+ ion environment
