Functional Keldysh theory of spin torques
(American Physical Society, 2007)
We present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism. We find that the nonequilibrium magnetization ...
Torque magnetometry study of metamagnetic transitions in single-crystal HoNi(2)B(2)C at T approximate to 1.9 K
(American Physical Society, 2007)
Metamagnetic transitions in single-crystal rare-earth nickel borocarbide HoNi(2)B(2)C have been studied at T approximate to 1.9 K with a Quantum Design torque magnetometer. This compound is highly anisotropic with a variety ...
Superconductivity in gallium-substituted Ba8Si46 clathrates
(American Physical Society, 2007)
We report a joint experimental and theoretical investigation of superconductivity in Ga-substituted type-I silicon clathrates. We prepared samples of the general formula Ba8Si46-xGax, with different values of x. We show ...
Laser-excited acoustic oscillations in silver and bismuth nanowires
(American Physical Society, 2007)
Coherent acoustic oscillations in Bi and Ag nanowire samples were studied with a femtosecond pump-probe technique and detection of the scattered light. The observed optical and acoustic properties reflect the nanostructure ...
Local control of magnetocrystalline anisotropy in (Ga,Mn)As microdevices: Demonstration in current-induced switching
(American Physical Society, 2007)
The large saturation magnetization in conventional dense moment ferromagnets offers a flexible means of manipulating the ordered state through demagnetizing shape anisotropy fields, but these dipolar fields, in turn, limit ...
Characterization of very-low density lipoprotein particle diameter dynamics in relation to egg production in a passerine bird

Apoptosis-Inducing Factor Participation in Bovine Macrophage Mycobacterium bovis-Induced Caspase-Independent Cell Death

D-sJ(2317) meson production in ultrarelativistic heavy ion collisions RID A-2398-2009
(American Physical Society, 2007)
Production of D-sJ(2317) mesons in relativistic heavy ion collisions at the BNL Relativistic Heavy Ion Collider is studied. Using the quark coalescence model, we first determine the initial number of D-sJ(2317) mesons ...
Forward Lambda production and nuclear stopping power in d+Au collisions at root s(NN)=200 GeV
(American Physical Society, 2007)
We report the measurement of Lambda and (Lambda) over bar yields and inverse slope parameters in d+Au collisions at root s(NN)=200 GeV at forward and backward rapidities (y=+/- 2.75), using data from the STAR forward time ...
