The ferromagnetic compound La{sub 3{minus}3x}Ca{sub 1+3x}Mn{sub 3}O{sub 10} with a triple perovskite structure can be successfully synthesized by using a thin-film growth method. Sputtered a-axis thin films with x=0.3 have been examined with respect to their magnetotransport properties. For the triple perovskite compound, we have observed the features, including the enhanced magnetoresistene (MR) effect and the characteristic low-temperature MR effect resulting from intragrain spin-polarized tunneling, which were reported for the double perovskite manganites. A comparison of the magnitude of these features in triple and double perovskite manganites suggests that the features are actually determined by the c-axis Mn{endash}O bond configuration in a layered-perovskite ferromagnet. {copyright} {ital 1997 American Institute of Physics.}
