Raman spectroscopic evidence for multiferroicity in rare earth nickelate single crystals
The rare earth nickelates RNiO_{3} are metallic at high temperatures and insulating and magnetically ordered at low temperatures. The low temperature phase has been predicted to be type II multiferroic, i.e., ferroelectric and magnetic order are coupled and occur simultaneously. Confirmation of thos...
