Exchange Biasing of the Ferromagnetic Semiconductor Ga1-xMnxAs
K. F. Eid, M. B. Stone, K. C. Ku +4
We demonstrate the exchange coupling of a ferromagnetic semiconductor (Ga1-xMnxAs) with an overgrown antiferromagnet (MnO). Unlike most conventional exchange biased systems, the bl…
Bose-Einstein Condensation of Helium and Hydrogen inside Bundles of Carbon Nanotubes
F. Ancilotto, M. M. Calbi, S. M. Gatica +1
Helium atoms or hydrogen molecules are believed to be strongly bound within the interstitial channels (between three carbon nanotubes) within a bundle of many nanotubes. The effect…
External control of the direction of magnetization in ferromagnetic InMnAs/GaSb heterostructures
X. Liu, W. L. Lim, L. V. Titova +10
In this paper, we demonstrate external control over the magnetization direction in ferromagnetic (FM) In_{1-x}Mn_{x}As/GaSb heterostructures. FM ordering with T_C as high as 50 K i…
Low Temperature Spin Freezing in Dy2Ti2O7 Spin Ice
J. Snyder, B. G. Ueland, J. S. Slusky +3
We report a study of the low temperature bulk magnetic properties of the spin ice compound Dy2Ti2O7 with particular attention to the (T < 4 K) spin freezing transition. While this…
Intriguing examples of inhomogeneous broadening
Francesco Ancilotto, M. Mercedes Calbi, Milton W. Cole +2
Three problems are considered in which inhomogeneous broadening can yield unusual consequences. One problem involves the energy levels of atoms moving within nanopores of nearly cy…
Structure optimization effects on the electronic properties of BiSrCaCuO
V. Bellini, F. Manghi, T. Thonhauser +1
We present detailed first-principles calculations for the normal state electronic properties of the high T superconductor BiSrCaCuO, by means of the linearized…
Formation of a quasiperiodic copper thin film
J. Ledieu, J. T. Hoeft, D. E. Reid +5
We have synthesised a thin film of copper with a quasi-periodic structure by the adsorption of copper atoms on the five-fold surface of the icosahedral quasicrystal Al-Pd-Mn at roo…
Origin of the "Waterfall" Effect in Phonon Dispersion of Relaxor Perovskites
J. Hlinka, S. Kamba, J. Petzelt +3
Inelastic neutron scattering study of the perovskite relaxor ferroelectric PZN:8%PT elucidates the origin of the previously reported unusual kink on the low frequency transverse ph…
Double Magnetic Transition in Pr0.5Sr0.5CoO3
R. Mahendiran, P. Schiffer
We report studies of polycrystalline samples of the metallic ferromagnet Pr0.5Sr0.5CoO3 through measurements of the magnetization, a.c. magnetic susceptibility, resistivity, and sp…
Relaxor ferromagnetic behavior below the antiferromagnetic transition in La0.5Ca0.5MnO3
R. Mahendiran, A. Maignan, C. Martin +2
A detailed reinvestigation of magnetization in La0.5Ca0.5MnO3 reveals that although a field of H = 7 T applied at T = 5 K after zero field cooling is insufficient to convert the lo…
Quantum-Classical Reentrant Relaxation Crossover in Dy2Ti2O7 Spin-Ice
J. Snyder, B. G. Ueland, J. S. Slusky +4
We have studied spin relaxation in the spin ice compound Dy2Ti2O7 through measurements of the a.c. magnetic susceptibility. While the characteristic spin relaxation time is thermal…
