| Description/Abstract | Giant magnetoresistance (GMR) at 300 K and 5.5 T with {Delta}{ital R}/{ital R}(0)=74% was observed in single crystals of La{sub 0.65}(PbCa){sub 0.35}MnO{sub 3}. The maximum GMR occurs exactly at the ferromagnetic--paramagnetic phase transition temperature ({ital T}{sub {ital c}}). For {ital T}{lt}{ital T}{sub {ital c}}, the {ital R}({ital T}) curve is closely related to the {ital M}({ital T}) curve. A sign change in the curvatures of {ital R}({ital H}) curves below and above {ital T}{sub {ital c}} has been observed, indicating that two different mechanisms are responsible for the magnetic scatterings of the carriers in two separate temperature regions. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}. |
