    • Precipitation Hardening in Ferroelectric Ceramics 

      Zhao, Changhao; Gao, Shuang; Yang, Tiannan; Scherer, Michael; Schultheiss, Jan; Meier, Dennis; Tan, Xiaoli; Kleebe, Hans-Joachim; Chen, Long-Qing; Koruza, Jurij; Rödel, Jürgen (Peer reviewed; Journal article, 2021)
      Domain wall motion in ferroics, similar to dislocation motion in metals, can be tuned by well-concepted microstructural elements. In demanding high-power applications of piezoelectric materials, the domain wall motion is ...
    • Pressure Control of Nonferroelastic Ferroelectric Domains in ErMnO<inf>3</inf> 

      Sandvik, Olav W.; Müller, Aaron Merlin; Ånes, Håkon W.; Zahn, Manuel; He, Jiali; Feibig, Manfred; Lottermoser, Thomas; Rojac, Tadej; Meier, Dennis; Schultheiß, Jan (Journal article; Peer reviewed, 2023)
      Mechanical pressure controls the structural, electric, and magnetic order in solid-state systems, allowing tailoring of their physical properties. A well-established example is ferroelastic ferroelectrics, where the coupling ...
    • PROCESSING AND PROPERTY ENGINEERING OF DOMAINS AND DOMAIN WALLS IN HEXAGONAL MANGANITES 

      Haas, Max (Master thesis, 2022)
      Topologisk beskyttede objekter har vakt oppmerksomhet innen mange forskningsom- råder. Fra kvantebiter til skyrmioner, fra superflytende helium til det tidlige universet, topologi spiller en avgjørende rolle. Det er ikke ...
    • The Third Dimension of Ferroelectric Domain Walls 

      Roede, Erik Dobloug; Shapovalov, Konstantin; Moran, Thomas; Mosberg, Aleksander Buseth; Yan, Zewu; Bourret, Edith; Cano, Andres; Huey, Bryan D.; Van Helvoort, Antonius; Meier, Dennis (Peer reviewed; Journal article, 2022)
      Ferroelectric domain walls are quasi-2D systems that show great promise for the development of nonvolatile memory, memristor technology, and electronic components with ultrasmall feature size. Electric fields, for example, ...
    • Topological defects in hexagonal manganites - Inner structure and emergent electrostatics 

      Holtz, Megan, E.; Shapovalov, Konstantin; Mundy, Julia; Chang, C. S.; Yan, Zewu; Bourret, Edith; Muller, David A.; Meier, Dennis; Cano, Andrés (Journal article; Peer reviewed, 2017)
      Diverse topological defects arise in hexagonal manganites, such as ferroelectric vortices, as well as neutral and charged domain walls. The topological defects are intriguing because their low symmetry enables unusual ...
    • Topological domain walls in helimagnets 

      Schoenherr, Peggy; Müller, Jan; Köhler, Laura; Rosch, Achim; Kanazawa, Naoya; Tokura, Yoshinori; Garst, Markus; Meier, Dennis (Journal article; Peer reviewed, 2018)
      Domain walls naturally arise whenever a symmetry is spontaneously broken. They interconnect regions with different realizations of the broken symmetry, promoting structure formation from cosmological length scales to the ...
    • An ultra-low field SQUID magnetometer for measuring antiferromagnetic and weakly remanent magnetic materials at low temperatures 

      Paulsen, Michael; Lindner, Julian; Klemke, Bastian; Beyer, Jörn; Fechner, Michael; Meier, Dennis; Kiefer, Klaus (Journal article, 2023)
      A novel setup for measuring magnetic fields of antiferromagnets (i.e., quadrupolar or higher-order magnetic fields) and generally weakly remanent magnetic materials is presented. The setup features a highly sensitive ...
