  • Effect of finite mean free path on spin-flip scattering rates near the critical point of magnetically ordered systems 

    Geldart, D. J. W., and K. De'Bell. 1985. "Effect of finite mean free path on spin-flip scattering rates near the critical point of magnetically ordered systems." Physical Review B (Condensed Matter) 32(5): 3285-8. Copyright © 1985 American Physical Society.
    The finite electron mean free path of conduction electrons is found to play an important role in determining spin-flip scattering rates, 1/sf, near a magnetic critical point. Small-momentum-transfer processes are suppressed ...

  • Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems 

    Fujiki, N. M., K. De'Bell, and D. J. W. Geldart. 1992. "Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems." Physical Review B (Condensed Matter) 45(9): 4686-94. Copyright © 1992 American Physical Society.
    Motivated by recent work on the critical resistivity of gadolinium, a detailed study has been made of the temperature dependence of the two-point vertex function in the large-momentum regime. The operator-project expansion ...
