    • Domain-wall engineering and topological defects in ferroelectric and ferroelastic materials 

      Nataf, Guillaume; Gregg, J Marty; Meier, Dennis Gerhard; Hlinka, Jiri; Salje, Ekhard K. H. (Journal article, 2020)
      Ferroelectric and ferroelastic domain walls are 2D topological defects with thicknesses approaching the unit cell level. When this spatial confinement is combined with observations of emergent functional properties, such ...

    • 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 ...

    • The interaction between vacancies and twin walls, junctions, and kinks, and their mechanical properties in ferroelastic materials 

      He, Xiaomei; Li, Suzhi; Ding, Xiangdong; Sun, Jun; Selbach, Sverre Magnus; Salje, Ekhard K. H. (Journal article; Peer reviewed, 2019)
      Vacancies strongly interact with twin boundaries and often change dramatically the properties of the ferroelastic material. However, the understanding of this behavior at an atomic-level is still deficient. Here we study ...
