• Interstitial oxygen as a source of p-type conductivity in hexagonal manganites 

      Skjærvø, Sandra Helen; Tjønneland Wefring, Espen; Nesdal, Silje K.; Gaukås, Nikolai Helth; Olsen, Gerhard Henning; Glaum, Julia; Tybell, Per Thomas Martin; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2016)
      Hexagonal manganites, h-RMnO3 (R=Sc, Y, Ho–Lu), have been intensively studied for their multiferroic properties, magnetoelectric coupling, topological defects and electrically conducting domain walls. Although point defects ...
    • Local dynamics of topological magnetic defects in the itinerant helimagnet FeGe 

      Dussaux, Antoine; Schoenherr, Peggy; Koumpouras, Konstantinos; Chico, Jonathan; Chang, Kevin; Lorenzelli, Luca; Kanazawa, Naoya; Tokura, Yoshinori; Garst, Markus; Bergman, Anders; Degen, Christian L.; Meier, Dennis (Journal article; Peer reviewed, 2016)
      Chiral magnetic interactions induce complex spin textures including helical and conical spin spirals, as well as particle-like objects such as magnetic skyrmions and merons. These spin textures are the basis for innovative ...
    • Piezoresponse force microscopy and nanoferroic phenomena 

      Gruverman, Alexei; Alexe, Marin; Meier, Dennis (Journal article; Peer reviewed, 2019)
      Since its inception more than 25 years ago, Piezoresponse Force Microscopy (PFM) has become one of the mainstream techniques in the field of nanoferroic materials. This review describes the evolution of PFM from an imaging ...
