The quest for magnetoelectric multiglasses
Abstract
A relatively unexplored phenomena in the area of multiferroics pertains to one where disorder, competing interactions, or frustration dictated by the underlying crystal symmetry could give rise to a multiglass state, with freezing in both the magnetic and polar sectors. A system of this nature should combine the properties of a magnetic spin/cluster glass and a ferroelectric relaxor, and is expected to exhibit novel phenomena like cross-coupled memory effects and the multicaloric effect. We propose the synthesis and characterization of a number of 4d and 5d transition metal oxides in an attempt to uncover possible multiglass states which they may harbor. To begin with, we propose the investigation of Iridium and Ruthenium based systems crystallizing in the double and triple perovskite structural classes. We also propose the setting up of nonlinear magnetic and dielectric susceptibility measurements set-ups as a means of evaluating the putative multiglass phase.
