    • Electrical half-wave rectification at ferroelectric domain walls 

      Schaab, Jakob; Skjærvø, Sandra Helen; Krohns, Stephan; Dai, Xiaoyu; Holtz, Megan, E.; Cano, Andrés; Lilienblum, Martin; Yan, Zewu; Bourret, Edith; Muller, David A.; Fiebig, Manfred; Selbach, Sverre Magnus; Meier, Dennis (Journal article; Peer reviewed, 2018)
      Domain walls in ferroelectric semiconductors show promise as multifunctional two-dimensional elements for next-generation nanotechnology. Electric fields, for example, can control the direct-current resistance and reversibly ...

    • Ferroelectricity in the multiferroic hexagonal manganites 

      Lilienblum, Martin; Lottermoser, Thomas; Manz, Sebastian; Selbach, Sverre Magnus; Cano, Andres; Fiebig, Manfred (Journal article, 2015)
      Since their discovery in 1963 the hexagonal manganites have consolidated their role as exotic ferroelectrics with astonishing functionalities. Their introduction as room-temperature device ferroelectrics was followed by ...

    • 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 ...

    • Magnetoelectric force microscopy on antiferromagnetic 180 degree domains in Cr2O3 

      Schoenherr, Peggy; Giraldo, L. M.; Lilienblum, Martin; Trassin, Morgan; Meier, Dennis; Fiebig, Manfred (Journal article; Peer reviewed, 2017)
      Magnetoelectric force microscopy (MeFM) is characterized as methodical tool for the investigation of antiferromagnetic domain states, in particular of the 180 ∘ variety. As reference compound for this investigation we use ...
