Abstract [en]

Two MHPOBC analogues, exhibiting ferroelectric and antiferroelectric phases, have been studied by means of frequency domain dielectric spectroscopy, time domain spectroscopy and electrooptic methods. Four relaxation processes at low frequencies and one broad spectrum at high frequencies have been revealed in the antiferroelectric phases of both substances studied by dielectric spectroscopy.
