TITLE:
Magnetodielectrics and multiferroics
SPEAKER:
Professor Gavin Lawes,
TIME: Thursday Mar. 1, 2007 at 4:00 PM
PLACE: George P. Williams, Jr. Lecture Hall, (Olin 101)
Wayne State University
Refreshments will be served at 3:30 PM in the lounge.
All interested persons are cordially invited to attend.
Over the past several years there has been a resurgence of interest in materials with coupled magnetic and dielectric properties, and particularly in systems with coexisting magnetic and ferroelectric order. These materials offer new avenues for exploring systems in which spin, charge, and structural degrees of freedom are strongly coupled, as well as providing new functionalities for designing novel magnetodielectric and magnetoelectric devices. I will present an overview of some recent work on investigating magnetodielectric coupling in a variety of insulating magnets, including SeCuO3 and CoCr2O4. I will also discuss how these experiments are relevant for understanding multiferroic systems, and discuss some results on this fascinating class of materials. In particular, I will focus on some recent results that provide insight into the underlying mechanism for spin-charge coupling in single-phase multiferroics.
