    • Large magnetorefractive effect in magnetite 

      ARORA, SUNIL; RAMOS, RAFAEL; SHVETS, IGOR (2010)
      We carried out a magneto-optical spectroscopic study of magnetite (Fe3O4) thin films and single crystals at optical wavelengths. We observed a relevant quadratic magneto-optic contribution that can be notably larger than ...

    • Proximity influence of a ferromagnet on the magnetoresistance of Cr film across a nonmagnetic layer 

      SHVETS, IGOR; MCEVOY, CIARAN (2004)
      (5 nm) Cr (100)/( x nm) MgO (100)/(30 nm) Fe3O4 (100) (1 < x < 6 nm), as well as (5 nm) Cr (100)/(5 nm) MgO (10 0) structures were grown on MgO (10 0) substrates using molecular beam epitaxy. The proximity influence of the ...

    • Reflectance anisotropy spectroscopy of magnetite (110) surfaces 

      MAUIT, OZHET; SMITH, CHRISTOPHER; FLEISCHER, KARSTEN; FARRELL, LEO; MCGILP, JOHN; SHVETS, IGOR (2014)
      Reflectance anisotropy spectroscopy (RAS) has been used to measure the optical anisotropies of bulk and thin-film Fe3O4(110) surfaces. The spectra indicate that small shifts in energy of the optical transitions, ...

    • Stability and capping of magnetite ultra-thin films 

      FLEISCHER, KARSTEN; MAUIT, OZHET; SHVETS, IGOR (2014)
      Ultrathin films of Fe3O4 have been grown epitaxially on nearly lattice matched MgO(001). The stability of 4 nm thick films in ambient air and under annealing in an oxygen atmosphere at 200◦C has been studied. By magneto ...
