hexagonal manganite [PDF]
Myung-Geun Han, Yimei Zhu, Lijun Wu, Toshihiro Aoki, Vyacheslav Volkov, Xueyun Wang, Seung Chul Chae, Yoon Seok Oh, Sang-Wook CheongField-induced switching of ferroelectric domains with a topological vortex configuration is studied by atomic imaging and electrical biasing in an electron microscope, revealing the role of topological defects on the topologically-guided change of domain-wall pairs in a hexagonal manganite.View original: http://arxiv.org/abs/1303.3593
