CME Seminar - Shixiong Zhang, Indiana University - Thursday, April 14th, 2016

[Robbins, Eric]

Please join us Thursday, April 14th for the Condensed Matter Experiment Seminar presented by Shixiong Zhang, Indiana University at 11:30am in the Smith Seminar Room (1080 PRB).  The title and abstract for the talk are below:




"Magnetism in Complex Iridates"

5d transition-metal oxides such as iridates have recently attracted growing interest because of their potential for realizing new topological phases (e.g. the Weyl semimetal phase) that arise from the interplay of strong spin-orbit interaction and electron correlation. In order to realize these topological states, it is essential to study the magnetic properties as the electronic structures are strongly coupled with the magnetic ground states. In this talk, I will present our recent studies of magnetic properties of some important iridates, including the pyrochlore iridates and the double- perovskite compounds. In particular, I will present our magnetic susceptibility measurements and electron spin resonance study that suggest the existence of novel magnetic ground states in these complex compounds. I will also discuss the potential origins of magnetic ordering at low temperatures.
