  We present a study of anisotropy of transport and magnetic properties in
La_{1-x}Ca_{x}MnO_{3} (x \approx 1/3) film prepared by pulsed-laser deposition
onto a LaAlO_{3} sunstrate. We found a non-monotonic dependence of
magnetoresistance (MR) on magnetic field H for both H perpendicular and
parallel to the film plane but perpendicular to the current. This rather
complex behavior of MR manifests itself at low temperatures, far below the
Curie temperature. Two main sources of MR anisotropy have been considered in
the explanantion of the results: (1) the existence of preferential directions
of magnetization (due to strains stemming from the lattice film-substrate
mismatch or other reasons); (2) dependence of resistance on the angle between
current and the magnetization, which is inherent in ferromagnets.
