Welcome
Our research in experimental condensed matter physics focuses on the properties of magnetic materials, and in particular on understanding the general conditions under which magnetic order is stabilized. We are interested not only on how magnetic moments forms or survive in the metallic environment, but also in the interplay of moment stability and magnetic order. Currently, we have three different projects ongoing in our group.
First, we have found that it is possible to use
composition, pressure, and large magnetic fields to suppress magnetic ordering
transitions to zero temperature, and we are studying the anomalous spatial and
temporal correlations which underlie the quantum critical phenomena associated
with these novel phase transitions.
Our second project seeks to understand the stability of magnetic moments and the magnetic order among small concentrations of magnetic ions placed in small gap insulators, where the number of moments and itinerant carriers mediating the magnetic interactions can be systematically varied.
Finally, we are investigating the properties of ensembles of magnetic nanoparticles, where the overall magnetic behavior is determined both by the intraparticle dynamics (controlled by particle size, shape, and composition) and the interactions among nanoparticles, controlled largely by the nanoparticle spacing and by the characteristics of the medium in which the nanoparticles are embedded.
