Abstract :
The dielectric properties of KTN under applied dc biasing fields were studied. Applications of fields caused the Curie temperature to shift toward higher temperatures and the value of the dielectric constant at the peak to be reduced. A field of 6 kV/cm resulted in a shift of the Curie point by 8°C. The loss tangent was similarly affected by the field. At the Curie temperature, the loss tangent was quite high, about 0.2. A field of 6 kV/cm reduced it by a factor of about 3.
