dc.description.abstract	Electrical resistivity behavior of single crystals as well as polycrystalline pellets of rare earth manganates has been investigated below the charge-ordering temperatures to understand the mechanism of conduction. The resistivity of both the single- and polycrystalline samples of Gd0.5Ca0.5MnO3 and Nd0.5Ca0.5MnO3 obey the T-1/4 law, characteristic of variable range hopping. A similar dependence is found in the hole-doped Pr0.6Ca0.4MnO3 as well, but the data of the electron-doped Pr0.4Ca0.6MnO3 do not seem to obey any T-1/n law satisfactorily. AC conductivity measurements also reflect the unusual nature of the electron-doped composition. (C) 2002 editions scientifiques et medicales Elsevier SAS. All rights reserved.	en_US
