The dielectric relaxation properties and freezing behavior of polar nanoregions (PNRs) of 0.24Pb(In 1/2 Nb 1/2 )O 3 -0.47Pb(Mg 1/3 Nb 2/3 )O 3 -0.29PbTiO 3 single crystals have been studied. The Burns temperature T B , permittivity maximum temperature T m , and freezing temperature T f were determined, respectively. It was found that the temperature-dependent dielectric constant can be well described by the Lorenz-type relationship in the ergodic phase due to the existence of PNRs. The diffuseness factor δ is >30 and is basically not dependent on crystal orientation. The frequency dependence of T m obeys the Vogel-Fulcher relationship. The residual effect of the poling electric field disappears and the remnant polarization has a sharp decrease near the freezing temperature T f .
