Conductivity Contrast and Tunneling Charge Transport in the Vortexlike Ferroelectric Domain Patterns of Multiferroic Hexagonal YMnO3
Ruff, E.; Krohns, S.; Lilienblum, M.; Meier, Dennis Gerhard; Fiebig, Manfred; Lunkenheimer, Peter; Loidl, Alois (Journal article, 2017)We deduce the intrinsic conductivity properties of the ferroelectric domain walls around the topologically protected domain vortex cores in multiferroic YMnO3. This is achieved by performing a careful equivalent-circuit ... -
Domain-Pattern Transfer across an Artificial Magnetoelectric Interface
De Luca, Gabriele; Schoenherr, Peggy; Mendil, Johannes; Meier, Dennis; Fiebig, Manfred; Trassin, Morgan (Journal article; Peer reviewed, 2018)Magnetoelectric interfaces provide efficient pathways for manipulating the magnetic order with low-power-consuming electric fields. A prime example of this is the voltage-controlled domain-pattern transfer from a multiferroic ... -
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 ... -
Frequency dependent polarisation switching in h-ErMnO3
Ruff, Alexander; Li, Ziyu; Loidl, Alois; Schaab, Jakob; Fiebig, Manfred; Cano, Andres; Yan, Zewu; Bourret, Edith; Glaum, Julia; Meier, Dennis; Krohns, Stephan (Journal article; Peer reviewed, 2018)We report an electric-field poling study of the geometric-driven improper ferroelectric h-ErMnO3. From a detailed dielectric analysis we deduce the temperature and frequency dependent range for which single-crystalline ... -
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 ... -
Local electric-field control of multiferroic spin-spiral domains in TbMnO3
Schoenherr, Peggy; Manz, Sebastian; Kuerten, Lukas; Shapovalov, Konstantin; Iyama, Ayato; Kimura, Tsuyoshi; Fiebig, Manfred; Meier, Dennis Gerhard (Journal article, 2020)Spin-spiral multiferroics exhibit a magnetoelectric coupling effects, leading to the formation of hybrid domains with inseparably entangled ferroelectric and antiferromagnetic order parameters. Due to this strong magnetoelectric ... -

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 ... -
Magnetoelectric inversion of domain patterns
Leo, Naemi; Carolus, Vera; White, Jonathan S.; Kenzelmann, Michel; Hudl, Matthias; Tolédano, Pierre; Honda, T.; Kimura, Tsuyoshi; Ivanov, S. A.; Weil, M.; Lottermoser, Thomas; Meier, Dennis; Fiebig, Manfred (Journal article; Peer reviewed, 2018)The inversion of inhomogeneous physical states has great technological importance; for example, active noise reduction relies on the emission of an inverted sound wave that interferes destructively with the noise of the ... -
