Study of the Layered Perovskite $Sr_3Ru_2O_7$ by STS and ARPES.
ORAL
Abstract
The Ruddlesden-Popper series, $Sr_{n+1}Ru_nO_{3n+1}$ exhibits a variety of electronic phases, including triplet superconductivity (n=1) or metamagnetism (n=2). Here we report studies of the electronic structure of the bilayered perovskite $Sr_3Ru_2O_7$ (n=2) by means of scanning tunneling spectroscopy. Special attention is given to the influence of titanium impurity atoms on the local electronic structure. A comparison with angle resolved photoemission experiments on the same set of samples is drawn.
