| Description/Abstract | La{sub 0.62}Tb{sub 0.05}Ca{sub 0.33}MnO{sub 3} and La{sub 0.6}Y{sub 0.07}Ca{sub 0.33}MnO{sub 3} have been studied in order to probe into the mechanisms responsible for the giant magnetoresistance ratios observed in this kind of compound. The experiments have shown a strong connection between the magnetotransport and magnetovolume properties. A large volume effect appears above {ital T}{sub {ital c}} which collapses with applied magnetic field or when the long range magnetic order sets in. Above {ital T}{sub {ital c}} the magnetostriction and magnetoresistance isotherms are highly correlated. Charge localization with local distortion appears to be responsible for the transport and volume properties at zero field. Charge mobility and a more normal volume dependence on temperature are restored by applying high enough magnetic fields. {copyright} {ital 1996 American Institute of Physics.} |
