  • Anisotropy of the critical magnetic susceptibility of gadolinium 

    Geldart, D. J. W., P. Hargraves, N. M. Fujiki, and R. A. Dunlap. 1989. "Anisotropy of the critical magnetic susceptibility of gadolinium." Physical Review Letters 62(23): 2728-31. Copyright © 1989 American Physical Society.
    The magnetic susceptibility along the c axis (xc) and in the basal plane (xb) has been measured on a single crystal of Gd in the reduced temperature range 410-4t1.310-2. Uniaxial anisotropy is observed. Magnetic dipole-dipole ...

  • Critical magnetic susceptibility of gadolinium 

    Hargraves, P., R. A. Dunlap, D. J. W. Geldart, and S. P. Ritcey. 1988. "Critical magnetic susceptibility of gadolinium." Physical Review B (Condensed Matter) 38(4): 2862-4. Copyright © 1988 American Physical Society.
    The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple ...

  • 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 ...

  • Heat capacity of gadolinium near the Curie temperature 

    Bednarz, G., D. J. W. Geldart, and M. A. White. 1993. "Heat capacity of gadolinium near the Curie temperature." Physical Review B (Condensed Matter) 47(21): 14247-59. Copyright © 1993 American Physical Society.
    High-resolution AC calorimetric data near the Curie point are reported for several single crystals of gadolinium. The critical temperature and the shape of the heat-capacity curve near Tc both depend on the sample-preparation ...
