A New Multiferroic Material: MnWO4

Strongly Correlated Electrons 2007-05-23 v1

Abstract

We report the multiferroic behaviour of MnWO4_4, a magnetic oxide with monoclinic crystal structure and spiral long-range magnetic order. Based upon recent theoretical predictions MnWO4_4 should exhibit ferroelectric polarization coexisting with the proper magnetic structure. We have confirmed the multiferroic state below 13 K by observing a finite electrical polarization in the magnetically ordered state via pyroelectric current measurements.
