Abstract
We have performed planar tunneling measurements on Sr3Ru2O7, which has a field-tuned metamagnetic quantum phase transition. Our previously reported work revealed an unusual oscillation in the tunneling magnetoresistance of junctions made on Sr3Ru2O7 single crystals [J. Hooper, Phys. Rev. Lett. 92, 257206 (2004)]. We here report further characterization of this intriguing phenomenon, revealing that the oscillation has a systematic dependence on the tunnel barrier, field orientation, and temperature. We discuss possible origins of this unusual oscillation phenomenon in light of these new experimental results.
