Abstract

We have investigated the structural, magnetic, and ferroelectric properties of magnetically frustrated multiferroic YMnO ₃ single crystals. The ferroelectric domain structures of YMnO ₃ samples were studied by piezoresponse force microscopy. Instead of domain vortex structure in stoichiometric crystals, YMnO _3-δ exhibits a random domain configuration with straight domain walls. In magnetic measurements, the YMnO _3-δ crystal shows typical antiferromagnetic behavior with higher Nel temperature and lower magnetization compared to the stoichiometric sample. The ordered oxygen vacancies dominate multiferroicity through tailoring the domain wall structure.
