摘要

Time-resolved thermoelectric power measurements on bulk single crystals with composition close to charge ordered compound Pr2/3Ca1/3MnO3 show a voltage transient V-2(t) for T < T-co, which is superimposed to and faster as the quasistatic thermovoltage decay V-3(t) which is usually the only transient observed with manganite ceramic. From V-3(t) we derive the heat conductivity k and thermopower S in the temperature range 90 K < T < 350 K. The extra transient is ascribed to the decay of an ambipolar charge distribution in trap states which appears only in the charged ordered regime of x = 0.37. First data on intrinsic and/or extrinsic trap level distributions are given. (C) 2004 Elsevier B.V. All rights reserved.
