    • Insulating improper ferroelectric domain walls as robust barrier layer capacitors 

      Puntigam, Lukas; Schultheiss, Jan; Strinic, Ana; Yan, Zewu; Bourret, Edith; Altthaler, Markus; Keszmarki, Istvan; Evans, Donald; Meier, Dennis Gerhard; Krohns, Stephan (Peer reviewed; Journal article, 2021)
      We report the dielectric properties of improper ferroelectric hexagonal (h-)ErMnO3. From the bulk characterization, we observe a temperature and frequency range with two distinct relaxation-like features, leading to high ...

    • Magnetic and geometric control of spin textures in the itinerant kagome magnet Fe3 Sn2 

      Altthaler, Markus; Lysne, Erik Nikolai; Roede, Erik Dobloug; Prodan, Lilian; Tsurkan, Vladimir; Kassem, Mohamed A.; Nakamura, Hiroyuki; Krohns, Stephan; Kézsmárki, István; Meier, Dennis Gerhard (Peer reviewed; Journal article, 2021)
      Magnetic materials with competing magnetocrystalline anisotropy and dipolar energies can develop a wide range of domain patterns, including classical stripe domains, domain branching, and topologically trivial and nontrivial ...
