We have studied the structural, magnetic, and electronic transport properties of (Sr_0.9Ca_0.1)₃Ru₂O₇ using single crystals grown by a floating-zone technique. The structure analysis by Rietveld refinements reveals that the Ca substitution for Sr intensifies the structure distortion; the rotation angle of the RuO₆ octahedron increases. This structure change tunes magnetic and transport properties dramatically. The magnetic ground state switches from an itinerant metamagnetic state for Sr₃Ru₂O₇ to a nearly ferromagnetic state for (Sr_0.9Ca_0.1)₃Ru₂O₇. The Fermi …
