Abstract
Relaxational behavior of ferroelectric telluric acid ammonium phosphat e crystals were investigated in the range 20 Hz to 1 MHz by means of l ow field measurements of epsilon' and tan delta in the vicinity of fer roelectric phase transitions at a number of frequencies. Results are c ompared with those for triglycine selenate, a much ''softer'' ferroele ctric material. The measuring field and frequency dependence of the ef fective potential barrier height for domain wall motion are compared i n both crystals.
