  • 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 ...

  • 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 ...
