Global formation of topological defects in the multiferroic hexagonal manganites
Meier, Quintin Noel; Lilienblum, Martin; Griffin, Sinead M; Conder, K; Pomjakushina, Ekaterina; Yan, Zewu; Bourret, Edith; Meier, Dennis; Lichtenberg, Frank; Salje, Ekhard K. H.; Spaldin, Nicola A.; Fiebig, Manfred; Cano, Andrés (Journal article; Peer reviewed, 2017)The spontaneous transformations associated with symmetry-breaking phase transitions generate domain structures and defects that may be topological in nature. The formation of these defects can be described according to the ... -
Local control of improper ferroelectric domains in YMnO 3
Kuerten, Lukas; Krohns, Stephan; Schoenherr, Peggy; Holeczek, Katharina; Pomjakushina, Ekaterina; Lottermoser, Thomas; Trassin, Morgan; Meier, Dennis Gerhard; Fiebig, Manfred (Peer reviewed; Journal article, 2020)Improper ferroelectrics are described by two order parameters: a primary one, driving a transition to long-range distortive, magnetic, or otherwise nonelectric order, and the electric polarization, which is induced by the ...
