Insights into puzzling materials using the infrared Hall effect

Professor John Cerne
SUNY, Buffalo, New York

Abstract: Strongly correlated materials ranging from diluted magnetic 
semiconductors (DMS) to transition-metal oxides, such as ruthenate 
perovskite (RP) compounds and high temperature superconductor cuprates 
(HTSC), are revolutionizing fundamental concepts in condensed matter physics 
and show great potential for applications to spin-based electronics and 
multifunctional devices. These materials exhibit unusual properties, such as 
carrier-mediated magnetism, metamagnetism, quantum criticality and non-Fermi 
liquid behavior that continue to challenge the condensed matter community. 
Despite the wide range of properties exhibited by these materials, they all 
exhibit anomalous behavior in dc Hall effect measurements. In this talk I 
will discuss why one should and how one can explore the Hall effect as a 
function of frequency using infrared magneto-polarimetry. Recent results on 
RP, DMS and HTSC materials will be presented and compared with theoretical 
predictions.
