  • Spin waves and quantum criticality in the frustrated XY pyrochlore antiferromagnet Er2Ti2O7 

    Ruff, J. P. C., J. P. Clancy, A. Bourque, M. A. White, et al. 2008. "Spin waves and quantum criticality in the frustrated XY pyrochlore antiferromagnet Er2Ti2O7." Physical Review Letters 101(14): 147205-147205. Copyright © 2008 American Physical Society.
    We report detailed measurements of the low temperature magnetic phase diagram of Er2Ti2O7. Heat capacity and time- of- flight neutron scattering studies of single crystals reveal unconventional low- energy states. Er3+ ...

  • Structural principles and amorphouslike thermal conductivity of Na-doped Si clathrates 

    Tse, JS, K. Uehara, R. Rousseau, A. Ker, et al. 2000. "Structural principles and amorphouslike thermal conductivity of Na-doped Si clathrates." Physical Review Letters 85(1): 114-117. Copyright © 2000 American Physical Society.
    The postulated low thermal conductivity and the possibility of altering the electronic conductivity of metal-doped clathrates with semiconducting host elements have stimulated great interest in exploring these compounds ...

  • Structural principles and amorphouslike thermal conductivity of Na-doped Si clathrates (vol 85, pg 114, 2000) 

    Tse, JS, K. Uehara, R. Rousseau, A. Ker, et al. 2001. "Structural principles and amorphouslike thermal conductivity of Na-doped Si clathrates (vol 85, pg 114, 2000)." Physical Review Letters 86(21): 4980-4980. Copyright © 2001 American Physical Society.

  • High-resolution, high-sensitive ac calorimeter. 

    Bednarz, Grzegorz, Brian Millier, and Mary Anne White. 1992. "High-resolution, high-sensitive ac calorimeter.." Review of Scientific Instruments 63(8): 3944-3952.
    A high-resoln., high-sensitivity, automated ac calorimeter capable of heat capacity measurements of very small samples (m < 20 mg) with a temp. resoln. of a few mK in the ac mode is described. This calorimeter also can be ...

  • Automated, small sample-size adiabatic calorimeter. 

    Van Oort, Michiel J. M., and Mary Anne White. 1987. "Automated, small sample-size adiabatic calorimeter.." Review of Scientific Instruments 58(7): 1239-1241.
    An automated adiabatic calorimeter is described with an internal vol. of 5 cm3, operable at 30-380 K. One of the main advantages of this calorimeter over others in use is the shorter down time during sample changes, due ...
