Abstract

With use of elastic neutron scattering, the creation of a new commensurate phase with modulation wave vector

δ = \frac{1}{8}

by the application of an external electric field along the ferroelectric axis in deuterated thiourea is demonstrated. The temperature range over which this induced phase exists (2.5 K at

E = 4000

V/cm) increases with increasing

E
