“…The non-ergodic, nonlinear and non-equilibrium phenomena, dependent on the heavy rare earth element, were found in rare earth nitrate crystals [9,10]. The meta-stability observed in lead nitrate was classified into the same category of those found in rare earth nitrate crystals.…”

“…Rare earth nitrate crystals R(NO 3 ) 3 6H 2 O (R = rare earth element) are of triclinic symmetry with the space group P 1 , and the crystal symmetry is independent of temperature above 193 K [8]. Kawashima et al [9] measured the electrical properties of rare earth nitrate crystals between 203.15 K and room temperature. They found meta-stable phenomena having non-ergodic nonlinear dynamical properties.…”

The measured alternating current (ac) electrical conductivity of lead nitrate [Pb(NO 3 ) 2 ] crystals in the frequency range 20 -10 6 Hz at temperature varying from 200 to 320 K shows anomalous temperature dependence, having meta-stability in the temperature range from 240 to 300 K. The dynamic properties have been extracted from these ac electrical data. The frequency exponents derived from the power law of the conductivity exhibit a singularity in this temperature variation range. A critical slowing down has been observed at temperatures near 275 K.
