ELECTRIC FIELD CONTROL OF THE ELASTIC COMPLIANCE IN LITHIUM THALLIUM TARTRATE

Abstract
In lithium thallium tartrate monohydrate it has been demonstrated that at temperatures close to the ferroelectric transition near 10 °K, the elastic compliance s44E may be controlled by an electric field applied in the [100] direction. The compliance changes by a factor of 25 for fields of order 10 kV/cm.
