Characteristics and the nature of the low-frequency dielectric response in moderately concetrated KTaO 3:Li.
The temperature-frequency behaviour of the complex permittivity of K 0.957Li 0.043TaO 3 was studied in detail. Below 250 K a pronounced relaxation-type dielectric dispersion occurs with two wide temperature maxima shifted to lower t...

Broad-band dielectric spectroscopy of relaxor ferroelectric Sr0.61 Ba0.39 Nb2 O6./sub
Relaxor properties were detected in the ?*c response, where an intense relaxation slows down from the microwave range (T>Tm) and broadens to low frequencies on cooling. IR modes show no anomalies in photon frequencies
