We report an emergent electronic and magnetic state in the bilayer ruthenate Ca3Ru2O7 upon doping with a small concentration of Ti on the Ru sites. In contrast to a quasi-two-dimensional metallic state in Ca3Ru2O7, which has an antiferromagnetic (AF) state formed by ferromagnetic (F) bilayers stacked antiferromagnetically along the c-axis, we find an insulating ground state with a "G"-type nearest-neighbor AF order in Ca3(Ru 1-xTix)2O7 for x 0.03. The close proximity of these two distinct electronic and magnetic states demonstrates unique competing magnetic interactions in Ca3Ru2O 7, which provides a rare opportunity to investigate the interplay between correlated metal physics and Mott physics.
