Dielectric Susceptibility of(KBr)0.50(KCN)0.50: Is It a Dipole Glass?

Abstract
Dielectric susceptibility measurements for the mixed crystal (KBr)0.50 (KCN)0.50 are reported in the frequency range 20 Hz<f<80 kHz. An anomaly is found at temperatures far below that where neutron and Brillouin studies find mode softening. The results are interpreted in terms of a possible dipole-glass phase that has been recently proposed for this system.
