摘要：
The Hall resistivity of epitaxial La2/3Ca1/3MnO3-delta 1 and bulk Nd2/3Sr1/3MnO3-delta 2 separates into a normal and an anomalous part. The anomalous Hall resistivity correlates with magnetisation data while the normal part suggests the use of a two-band model for these perovskites. Single carrier concentrations and mobilities are p less than or equal to 0.75 x 10(21) cm(-3) (4.2 K, Nd-Sr) and p less than or equal to 6.4 x 10(22) cm(-3) (4.2 K, La-Ca) and then mobilities at 4.2 K, B = 0 are mu(p) greater than or equal to 1.03 cm(2)/(V s) (Nd-Sr) or greater than or equal to 0.44 cm(2)/(V s) (La-Ca).
