      The combination of standard wafer-scale semiconductor processing with the properties of functional oxides opens up to innovative and more efficient devices with high value applications which can be produced at large scale. ...
    • Low-temperature spin excitations in frustrated ZnCr2O4 probed by high-field thermal conductivity 

      Zhou, Haidong; Zhao, Z. Y.; Sun, X. F.; Nieto Suárez, Marina; Rivas Murias, Beatriz; Tsurkan, Vladimir; Deisenhofer, Joachim; Zapf, Vivien; Rivadulla, Francisco (APS Physics, 2013)
      The magnetoelastic excitations of spin frustrated ZnCr2O4 are studied by the magnetic field dependence of the thermal conductivity k down to 50 mK. Above the first-order magnetostructural transition at TN,S≈ 12.5 K, spin ...
    • Magnetic Field Induced Transition in Vanadium Spinels 

      Mun, E.D.; Chern, Gia-Wei; Pardo, Victor; Rivadulla, Francisco; Sinclair, R.; Zhou, Haidong; Zapf, Vivien; Batista, Cristian D. (2014)
      We study vanadium spinels AV2O4 (A=Cd,Mg) in pulsed magnetic fields up to 65 T. A jump in magnetization at μ0H≈40 T is observed in the single-crystal MgV2O4, indicating a field induced quantum phase transition between ...

      Kuntscher, Christine; Rabia, Kaneez; Forthaus, M.K.; Abd-Elmeguid, M. M.; Rivadulla, Francisco; Kato, Y.; Batista, Cristian D. (APS Physics, 2012)
      A2+V2O4 spinels provide a unique opportunity for studying the evolution of the charge gap of Mott insulators that approach the itinerant electron limit under the application of external pressure. Here we report ...
    • Orbital, charge, and spin couplings in Ru 25+O9 dimers of Ba3CoRu2O9 

      Zhou, Haidong; Kiswandhi, Andhika; Barlas, Yafis; Brooks, James; Siegrist, Theo Max; Li, G.; Balicas, Luis; Cheng, J. G.; Rivadulla, Francisco (APS Physics, 2012)
      e magnetic, transport, and structural properties of cold-pressed Ba3CoRu2O9 show (i) an antiferromagnetic transition, (ii) a semiconductor-semiconductor electronic transition where the resistivity is dominated by the ...
    • Oxygen vacancies in strained SrTiO 3 thin films: Formation enthalpy and manipulation 

      Iglesias, L.; Sarantopoulos, Alexandros; Magén, Cesar; Rivadulla, Francisco (APS Physics, 2017)
      We report the enthalpy of oxygen vacancy formation in thin films of electron-doped SrTiO 3 , under different degrees of epitaxial stress. We demonstrate that both compressive and tensile strain decrease this energy at ...
    • Polymer assisted deposition of epitaxial oxide thin films 

      Vila-Fungueiriño, José M.; Rivas Murias, Beatriz; Rubio-Zuazo, Juan; Carretero-Genevrier, Adrián; Lazzari, Massimo; Rivadulla, Francisco (Royal Society of Chemistry, 2018)
      Chemical solution methods for thin-film deposition constitute an affordable alternative to high-vacuum physical technologies, like Sputtering, Pulsed Laser Deposition (PLD) or Molecular Beam Epitaxy (MBE). Particularly, ...
    • Thermoelectric properties of heavy-element doped CrN 

      Quintela, C. X.; Rodríguez-González, Benito; Rivadulla, Francisco (AIP Publishing, 2014)
      CrN was doped with Mo and W to study the effect of heavy elements alloying on its thermoelectric properties. An spontaneous phase segregation into Mo- and W-rich regions was observed even at the lowest concentrations probed ...
