  • Helical magnetic order in MnSi thin films 

    Karhu, E. A.; Kahwaji, S.; Robertson, M. D.; Fritzsche, H.; Kirby, B. J.; Majkrzak, C. F.; Monchesky, T. L. (American Physical Society, 2011-08/01)
    We present a study of the magnetic structure of crystalline MnSi(111) thin films grown by molecular beam epitaxy. A combination of polarized neutron reflectometry (PNR) and superconducting quantum interference device ...

  • Local structure and magnetic properties of B2- and B20-like ultrathin Mn films grown on Si(001) 

    Kahwaji, S.; Gordon, R. A.; Crozier, E. D.; Monchesky, T. L. (American Physical Society, 2012-01/01)
    The structural and magnetic properties of ultrathin Mn layers deposited onto Si(001) by molecular beam epitaxy at low temperature are reported. X-ray absorption fine structure studies reveal that the structure of the ...

  • Magnetic properties of Co/GaAs(110) 

    Monchesky, T. L.; Unguris, J. (APS through AIP, 2006-12/15)
    We observed three magnetic states of an ultrathin, atomically well-ordered Co film grown on a cleaved GaAs(110) substrate. For a Co thickness less than 3.4 monolayers (ML), we find a ferromagnetically dead layer associated ...

  • Magnetoresistance and magnetic properties of Fe/Cu/Fe/GaAs(100) 

    Monchesky, T. L.; Heinrich, B.; Urban, R.; Myrtle, K.; Klaua, M.; Kirschner, J. (APS through AIP, 1999-10/01)
    A procedure for growth of smooth As free Fe surfaces on (46)-GaAs(100) is presented. Ferromagnetic resonance (FMR) revealed that the Fe films have anisotropies equal to bulk Fe, modified only by interface anisotropies. The ...

  • Role of interfaces in the magnetoresistance of Au/Fe/Au/Fe multilayers 

    Weinberger, P.; Zabloudil, J.; Hammerling, R. H.; Szunyogh, L.; Monchesky, T. L.; Heinrich, B. (APS through AIP, 2003-02/01)
    By using the fully relativistic spin-polarized screened Korringa-Kohn-Rostoker method and the corresponding Kubo-Greenwood equation resistivities and the giant magnetoresistance are evaluated for Fe/Au/Fe/Au spin valves ...

  • Spin-dependent transport in Fe and Fe/Au multilayers 

    Monchesky, T. L.; Enders, A.; Urban, R.; Myrtle, K.; Heinrich, B.; Zhang, X. -G; Butler, W. H.; Kirschner, J. (APS through AIP, 2005-06/01)
    In situ resistance measurements of epitaxial Fe layers and Au/Fe bilayers were used to quantify the scattering in giant magnetoresistance (GMR) spin valve structures. The semiclassical Boltzmann transport equation, ...

  • Structure and magnetic properties of MnSi epitaxial thin films 

    Karhu, E.; Kahwaji, S.; Monchesky, T. L.; Parsons, C.; Robertson, M. D.; Maunders, C. (American Physical Society, 2010-11/01)
    We report on the correlation between the magnetic and structural properties of epitaxial MnSi (111) thin films grown by solid-phase epitaxy on Si (111) substrates. The Si (111) substrate, with a surface unit cell that is ...
