Abstract
We have studied the transport properties of La0.6Re0.1Ca0.3MnO3 (Re = Pr, Sm, Gd, Dy) at low temperature down to 4.2 K with fixed doping con centration. The temperature at which the peak resistivity appears, shi fts to lower temperature as the ionic radii of the rare earth ions dec rease. The samples exhibit a resistivity minimum at low temperature de pending on the nature of the substituted rare earth ions. The temperat ure dependence of resistivity at low temperature has been interpreted in terms of electron-electron interaction. (C) 1998 Elsevier Science L td. All rights reserved.
