  • Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions 

    Geldart, D. J. W., and D. Neilson. 2003. "Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions." Physical Review B (Condensed Matter and Materials Physics) 67(4): 45310-1. Copyright © 2003 American Physical Society.
    The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ...

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

    Monchesky, T. L., B. Heinrich, R. Urban, K. Myrtle, et al. 1999. "Magnetoresistance and magnetic properties of Fe/Cu/Fe/GaAs(100)." Physical Review B (Condensed Matter) 60(14): 10242-51. doi:10.1103/PhysRevB.60.10242
    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 ...

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

    Monchesky, T. L., A. Enders, R. Urban, K. Myrtle, et al. 2005. "Spin-dependent transport in Fe and Fe/Au multilayers." Physical Review B (Condensed Matter and Materials Physics) 71(21): 214440-1. doi:10.1103/PhysRevB.71.214440
    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, ...
