Influence of /spl gamma/-ray irradiation on the thermochromic phase transition in diethylammoniumtetrachlorocuprate

Influence of /spl gamma/-ray irradiation on the thermochromic phase transition in diethylammoniumtetrachlorocuprate

The influence of /spl gamma/-ray irradiation on the phase transition temperature in (NH/sub 2/(C/sub 2/H/sub 5/)/sub 2/)/sub 2/CuCl/sub 4/ crystals was investigated. It has been ascertained that irradiation at room temperature leads to increase of transition temperature T/sub 1/. Contrary to this, i...

Beschreibung
Zusammenfassung:The influence of /spl gamma/-ray irradiation on the phase transition temperature in (NH/sub 2/(C/sub 2/H/sub 5/)/sub 2/)/sub 2/CuCl/sub 4/ crystals was investigated. It has been ascertained that irradiation at room temperature leads to increase of transition temperature T/sub 1/. Contrary to this, irradiation just below T/sub 1/ is followed by decreasing of transition temperature. Observed effects are connected with breaking of H-bonds and with corresponding change of Cu/sup 2+/ ion environment.
