Doping-Driven Collapse of the SDW Correlation Gap in SmFeAsOF
Scott C. Riggs, R. D. McDonald, J. B. Kemper +8
We report the Hall resistivity, of polycrystalline SmFeAsOF for four different fluorine concentrations from the onset of superconductivity through the collap…
Log-T divergence and Insulator-to-Metal Crossover in the normal state resistivity of fluorine doped SmFeAsO1-xFx
S. C. Riggs, J. B. Kemper, Y. Jo +8
We report the resistivity of a series of fluorine-doped SmFeAsO1-xFx polycrystalline superconductors in magnetic fields up to 60T. For underdoped samples (x < 0.15), the low temper…
Using magnetostriction to measure the spin-spin correlation function and magnetoelastic coupling in the quantum magnet NiCl-4SC(NH)
V. S. Zapf, V. F. Correa, P. Sengupta +9
We report a method for determining the spatial dependence of the magnetic exchange coupling, , from magnetostriction measurements of a quantum magnet. The organic Ni …
Unusual compressibility in the negative-thermal-expansion material ZrW2O8
C. Pantea, A. Migliori, P. B. Littlewood +5
The negative thermal expansion (NTE) compound ZrW2O8 has been well-studied because it remains cubic with a nearly constant, isotropic NTE coefficient over a broad temperature range…
Low-frequency Einstein mode in the zero-expansion material YbGaGe
