Abstract
The resistivity of La0.82Ca0.18MnO3 single crystal has been investigated as a function of external magnetic field and separately under an applied curr ent flow. The measurements were carried out at various temperatures below a nd above the ferromagnetic transition temperature T-C. It has been found th at the dynamic electroresistance exhibits stunning similarities to the colo ssal magnetoresistance at the corresponding temperatures. The correlation o bserved between the electric- and magnetic-field effects is attributed to e lectrically induced magnetoresistance. (C) 2001 American Institute of Physi cs.
