Abstract: The dielectric permittivity εr and loss of Pb(In 1/2 Nb 1/2 )O 3 -Pb(Mg 1/3 Nb 1/3 )O 3 ceramics (PIN-PMN) with compositions 40/60 and 70/30 was found to exhibit a typical relaxor behaviour. At 1 kHz, a peak in εr is observed at about 20C for 40/60 and 30C for 70/30, at which εr has values of 10000 and 5000, respectively. At 1 kHz, the loss tangent at the peak is about 0.1 and increases slightly with increasing frequency. Hysteresis measurements performed at room temperature at a frequency 50 Hz and under a maximum electrical field of 2 MV/m show a very slim loop for 40/60 and almost no loop for 70/30. The maximum polarization attained was 20 μC/cm 2 while the remanent polarization was less than 2 μC/cm 2 . The field-related electrostrictive coefficient M 11 for 40/60 was found to be 1.2×10 -16 m 2 /V 2 , which is of the same order of magnitude as those of the best PMN-relaxor solid solutions. The polarization-related electrostrictive coefficient Q 11 , calculated according to the relation Q 11 = M 11 / ε2 , was 1.5×10-2 m 4 /C 2.
