Abstract
The linear epsilon*(1) and the third harmonic complex dielectric constant e psilon*(3) in PbM1/3Nb2/3O3 (PMN) single crystal were measured as a functio n of frequency and temperature in a small electric field. The dielectric di spersion of epsilon*(3) was studied and the characteristic relaxation time together with the static dielectric nonlinearity were determined as a funct ion of the temperature. The static dielectric nonlinearity beta (s) is incr easing with decreasing temperature in the temperature range 266-242 K, whil e the relaxation time follows the Vogel-Fulcher law.
