We have investigated the effect of epitaxial strain on the electrical and magnetic properties of high quality Ca 2RuO 4 films on LaAlO 3 (001) substrates. The films exhibit low temperature itinerant ferromagnetic ground state and significantly suppressed metal-insulator transition due to epitaxial strain. An anomaly in the in-plane resistivity was also observed near the Néel temperature. Symmetry analysis of anisotropic magnetoresistance suggests a phase coexistence of ferromagnetic metal and antiferromagnetic insulator in ground state.
