We present detailed Hall effect, planar Hall effect and resistance measurem
ents of an epitaxial La0.67Ca0.33MnO3 thin film. In the ferromagnetic regim
e the transverse voltage shows a similar dependence on the external magneti
c field when it is applied perpendicular to (Hall effect) and in the plane
of the film (planar Hall effect). By this observation it is established tha
t the anomalous Hall effect is not the main origin of the transverse magnet
ovoltage. It is the anisotropic magnetoresistance (AMR), which we observe i
n both the longitudinal and the planar Hall configuration that: causes the
transverse magnetovoltage. (C) 1998 Elsevier Science Ltd. All rights reserv
