Abstract

We describe transport measurements in single-crystal. high-purity Ca3Ru2O7. The observation of a large linear magnetoresistance together with low frequency quantum oscillations is shown to be consistent with a small volume Fermi surface incompletely gapped by density wave formation. This complements previous ARPES experiments. The quantum oscillations are more pronounced in the Hall signal than in the longitudinal resistivity. This unusual observation is also explained by the peculiar electronic structure in this material. We remark oil the similarity between our observations in Ca3Ru2O7 and the observations of quantum oscillations in the underdoped cuprate superconductors.
