• 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 ...
    • Unconventional Continuous Structural Disorder at the Order-Disorder Phase Transition in the Hexagonal Manganites 

      Skjærvø, Sandra Helen; Meier, Quintin Noel; Feygenson, Mikhail; Spaldin, Nicola A.; Billinge, Simon J. L.; Božin, Emil S.; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2019)
      The improper ferroelectricity in YMnO3 and other related multiferroic hexagonal manganites is known to cause topologically protected ferroelectric domains that give rise to rich and diverse physical phenomena. The local ...
