The Kagome-staircase lattice: Magnetic ordering in Ni3V2O8 and Co3V2O8
N. Rogado, G. Lawes, D. A. Huse +2
Ni3V2O8 and Co3V2O8 have spin-1 and spin-3/2 magnetic lattices that are a new anisotropic variant of the Kagome net, wherein edge-sharing MO6 octahedra form the rises and rungs of…
Free and Trapped Injected Carriers in C60 Crystals
V. Y. Butko, A. P. Ramirez, C. Kloc
We report on the conductance from two-contact carrier injection in C60 single crystals. In the nonlinear regime, the current and voltage obey a power law, I \~ V^m, where m can be…
Colossal Dielectric Constants in Braced Lattices with Defects
A. P. Ramirez, G. Lawes, V. Butko +2
The dielectric constant of CaCu3Ti4O12 is measured with a different electrode geometry than previous measurements. Similar colossal values are obtained showing that they are "intri…
Structure and Superconductivity in Zr-Stabilized, Nonstoichiometric Molybdenum Diboride
L. E. Muzzy, M. Avdeev, G. Lawes +5
The structure and physical properties of the Zr-stabilized, nonstoichiometric molybdenum diboride superconductor are reported. Good quality material of the diboride structure type…
Epitaxial Thin Films of the Giant-Dielectric-Constant Material CaCu_3Ti_4O_{12} Grown by Pulsed-laser Deposition
W. Si, E. M. Cruz, P. D. Johnson +3
Pulsed-laser deposition has been used to grow epitaxial thin films of the giant-dielectric-constant material CaCu_3Ti_4O_{12} on LaAlO_3 and SrTiO_3 substrates with or without vari…
Joule heating of dilute 2D holes in a GaAs quantum well
Xuan P. A. Gao, Allen P. Mills, Arthur P. Ramirez +3
We present measurements of the Joule heating of a 2D hole gas (2DHG) formed in a 30nm GaAs quantum well. The hole density is in the range (4.6-18.9)*10^9cm^-2 and exhibits an appar…
