Abstract
The Hall resistivity ρ H and magnetoresistance of La 2/3 Sr 1/3 MnO 3 (T C ∼360 K) have been measured at temperatures up to 300 K in fields to 6 T. The linear correlation between the anomalous Hall coefficient R s and the longitudinal resistivity ρ related to skew scattering is found. The change of the anomalous part is attributed to the thermal spin fluctuation that could be described by an empirical relation R s ∝[M(0)-M(T)]. The correlation among R s , ρ, and [M(0)-M(T)] directly suggests that the dependence of resistivity may be described by the scattering due to thermal spin disorder. ©1999 The American Physical Society.
