Intended Audience:

Correlated electron oxides remain a foremost area of research, principally because they host essentially the entirety of contemporary condensed matter science — superconductivity, magnetism, multiferroicity, topological protection, etc. In this talk I will discuss some recent work in a few areas of transition metal oxide materials physics: Specifically, I will describe our recent work on iridates, in particular magnetic properties of the quantum spin liquid candidate Na2IrO3. This will include some discussion of our attempts to create related phases. I will then diverge to discuss some of the new materials we are currently working on that have become accessible to us through high pressure floating zone growth, focusing on a new class of nickelates with charge stripes and close-to-cuprate electronic structure. The hope is to give an appreciation of the kinds of materials that might be newly available as a consequence of this technique, to provide a view on the materials strategies of interest to our group and hopefully to pique the interest of potential collaborators at QMI.
