  • Magnetization reversal and confinement effects across the metamagnetic phase transition in mesoscale FeRh structures 

    Arregi Uribeetxebarria, Jon Ander; Horký, Michal; Fabianová, Kateřina; Tolley, Robert; Fullerton, E.E.; Uhlíř, Vojtěch (IOP PUBLISHING LTD, 2018-03-14)
    The effects of mesoscale confinement on the metamagnetic behavior of lithographically patterned FeRh structures are investigated via Kerr microscopy. Combining the temperatureand field-dependent magnetization reversal of ...
  • Single-layer graphene on epitaxial FeRh thin films 

    Uhlíř, Vojtěch; Pressacco, Frederico; Arregi Uribeetxebarria, Jon Ander; Procházka, Pavel; Průša, Stanislav; Potoček, Michal; Šikola, Tomáš; Čechal, Jan; Bendounan, Azzedine; Sirotti, F. (ELSEVIER, 2020-06-01)
    Graphene is a 2D material that displays excellent electronic transport properties with prospective applications in many fields. Inducing and controlling magnetism in the graphene layer, for instance by proximity of magnetic ...
  • Spin stress contribution to the lattice dynamics of FePt 

    von Reppert, Alexander; Willig, Lisa; Pudell, Jan Etienne; Zeuschner, Steffen Peer; Sellge, Gabriel; Ganss, Fabian; Hellwig, Olaf; Arregi Uribeetxebarria, Jon Ander; Uhlíř, Vojtěch; Crut, Aurelien; Bargheer, Matias (AAAS, 2020-06-01)
    Invar-behavior occurring in many magnetic materials has long been of interest to materials science. Here, we show not only invar behavior of a continuous film of FePt but also even negative thermal expansion of FePt ...
  • Stable room-temperature ferromagnetic phase at the FeRh(100) surface 

    Pressacco, Frederico; Uhlíř, Vojtěch; Gatti, Matteo; Bendounan, A.; Fullerton, E.E.; Sirotti, F. (Springer Nature, 2016-03-03)
    Interfaces and low dimensionality are sources of strong modifications of electronic, structural, and magnetic properties of materials. FeRh alloys are an excellent example because of the first-order phase transition taking ...
  • Subpicosecond metamagnetic phase transition in FeRh driven by non-equilibrium electron dynamics 

    Pressacco, Frederico; Sangalli, Davide; Uhlíř, Vojtěch; Kutnyakhov, Dmytro; Arregi Uribeetxebarria, Jon Ander; Agustsson, Steinn Ymir; Brenner, Günter; Redlin, Harald; Heber, Michael; Vasilyev, Dmitry; Demsar, Jure; Schönhense, Gerd; Gatti, Matteo; Marini, Andrea; Wurth, Wilfried; Sirotti, Fausto (Nature Portfolio, 2021-08-24)
    In FeRh, it is possible to optically drive a phase transition between ferromagnetic (FM) and anti-ferromagnetic (AFM) ordering. Here, using a combination of photoelectron spectroscopy and ab-initio calculations, the authors ...
