    • Dislocation-Driven Relaxation Processes at the Conical to Helical Phase Transition in FeGe 

      Schoenherr, Peggy; Stepanova, Mariia; Lysne, Erik Nikolai; Kanazawa, Naoya; Tokura, Yoshinori; Bergman, Anders; Meier, Dennis Gerhard (Journal article, 2021)
      The formation of topological spin textures at the nanoscale has a significant impact on the long-range order and dynamical response of magnetic materials. We study the relaxation mechanisms at the conical-to-helical phase ...

    • 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 ...

    • Electrostatic potential mapping at ferroelectric domain walls by low-temperature photoemission electron microscopy 

      Schaab, Jakob; Shapovalov, Konstantin; Schoenherr, Peggy; Hackl, Johanna; Khan, Muhammad Imtiaz; Hentschel, Mario; Yan, Zewu; Bourret, Edith; Schneider, Claus M.; Nemsak, Slavomír; Stengel, Massimiliano; Cano, Andrés; Meier, Dennis (Journal article; Peer reviewed, 2019)
      Low-temperature X-ray photoemission electron microscopy (X-PEEM) is used to measure the electric potential at domain walls in improper ferroelectric Er0.99Ca0.01MnO3. By combining X-PEEM with scanning probe microscopy and ...

    • 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 dynamics of topological magnetic defects in the itinerant helimagnet FeGe
