Quantum effects at TSCC1-xBx monocrystals: The influence of an external electric field on the permittivity peak

The results of model calculations and of experimental investigations of the shift of the temperature T_M of the maximum of the permittivity ε_b due to an external electric d.c. field on tris-sarcosine calcium chloride_1-x bromide_x (TSCC_1-xB_x) monocrystals with different concentrations x are described. It is shown that in the low temperature region a marked enhancement of the response of the permittivity maximum to an external electric d.c. field is caused by quantum effects.
