Abstract

The far infrared transmission between 5 and 140 cm⁻¹ of Rb₂ZnBr₄ has been measured as a function of temperature from 4 to 400 K. We have observed a temperature dependent mode, which broadens strongly with increasing temperature. Moreover, we have found strong indications of a new phase transition at 50 K.
