Abstract ： The travelling wave method has been used to measure the drift mobility in the paramagnetic-insulator state of La0.75 Sr0.11 Ca0.14 MnO3 films. The thermal activation of the drift mobility in manganites has been measured for the first time. The mobility varies from 2.5×10-2 cm2 /Vs at 310K to about 9.2×10-2 cm2 /Vs at 400K. The Arrhenius behaviours of the conductivity and drift mobility indicate that the transport process in manganites above the Curie temperature is dominated by the thermally assisted hopping of small polarons.
