  • Research Update: Focused ion beam direct writing of magnetic patterns with controlled structural and magnetic properties 

    Urbánek, Michal; Flajšman, Lukáš; Křižáková, Viola; Gloss, Jonáš; Horký, Michal; Schmid, Michael; Varga, Peter (AIP Publishing, 2018-06-01)
    Focused ion beam irradiation of metastable Fe78Ni22 thin films grown on Cu(100) substrates is used to create ferromagnetic, body-centered cubic patterns embedded into paramagnetic, face-centered-cubic surrounding. The ...
  • 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 ...
  • Control of domain structure and magnetization reversal in thick Co/Pt multilayers 

    Fallarino, Lorenzo; Oelschlägel, Antje; Arregi Uribeetxebarria, Jon Ander; Bashkatov, Aleksander; Samad, Fabian; Böhm, B.; Chesnel, Karine; Hellwig, Olav (American Physical Society, 2019-01-25)
    We present a study of the magnetic properties of [Co(3.0 nm)/Pt(0.6nm)]N multilayers as a function of Co/Pt bilayer repetitions N. Magnetometry investigation reveals that samples with N 15 exhibit two characteristic magnetization ...
  • Laser induced phase transition in epitaxial FeRh layers studied by pump-probe valence band photoemission 

    Pressacco, Frederico; Uhlíř, Vojtěch; Gatti, Matteo; Nicolaou, Alessandro; Bendounan, Azzedine; Arregi Uribeetxebarria, Jon Ander; Patel, Sheena K. K.; Fullerton, E.E.; Krizmancic, Damjan; Sirotti, F. (AIP Publishing, 2018-05-01)
    We use time-resolved X-ray photoelectron spectroscopy to probe the electronic and magnetization dynamics in FeRh films after ultrafast laser excitations. We present experimental and theoretical results which investigate ...
  • 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 ...
  • The growth of metastable fcc Fe78Ni22 thin films on H-Si(100) substrates suitable for focused ion beam direct magnetic patterning 

    Gloss, Jonáš; Horký, Michal; Křižáková, Viola; Flajšman, Lukáš; Schmid, Michael; Urbánek, Michal; Varga, Peter (Elsevier, 2019-03-01)
    We have studied the growth of metastable face-centered-cubic, non-magnetic Fe78Ni22 thin films on silicon substrates. These films undergo a magnetic (paramagnetic to ferromagnetic) and structural (fcc to bcc) phase ...
