Abstract

Transition metal oxides, due to their rich structural chemistry, delicate competition between different low temperature electronic and magnetic states, and strong coupling between crystal structure and physical properties, present many opportunities for solid state chemists to impact fundamental questions in condensed matter physics. In this talk, I will first present a general introduction to superconducting materials and triangular magnetic lattices, and then will describe our work on the structural, electronic, and magnetic characterization of the recently discovered NaxCoO2 × yH2O superconductor, which is based on a triangular planar lattice of cobalt oxide and dielectric water layers separating the superconducting planes.
