  • Critical exponents and amplitude ratios from electrical resistivity measurements of dysprosium 

    Malmstrom, G., and D. J. W. Geldart. 1980. "Critical exponents and amplitude ratios from electrical resistivity measurements of dysprosium." Physical Review B (Condensed Matter) 21(3): 1133-8. Copyright © 1980 American Physical Society.
    Resistive anomalies in helical antiferromagnets are shown to reflect the temperature dependence of the specific heat sufficiently close to the Neel temperature. The temperature dependence of superzone energy gaps does not ...
  • Dipole-dipole interactions and the critical resistivity of gadolinium 

    Geldart, D. J. W., K. De'Bell, J. Cook, and M. J. Laubitz. 1987. "Dipole-dipole interactions and the critical resistivity of gadolinium." Physical Review B (Condensed Matter) 35(16): 8876-9. Copyright © 1987 American Physical Society.
    Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ...
  • Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals 

    MacDonald, A. H., R. Taylor, and D. J. W. Geldart. 1981. "Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals." Physical Review B (Condensed Matter) 23(6): 2718-30. Copyright © 1981 American Physical Society.
    The Umklapp fraction, , for electron-electron scattering in the alkali metals has been calculated using first-principles pseudopotentials. Both Coulomb scattering and phonon-exchange scattering have been included. For a ...
