Viewpoint: Attractive vortices

Ernst Helmut Brandt、Shi‐Ping Zhou2009-03-16OpenAlex

Decoration experiments of the two-gap superconductor MgB2 show evidence for long-range attraction between vortices in a superconducting mixed state, which is interpreted as coexisting type-I and type-II superconductivity.

The role of partial clustering for frustration in a binary 2D colloidal glass former

Florian Ebert、G. Maret、Peter Keim2009-03-16arXiv (Cornell University)

A mixture of two types of super-paramagnetic colloidal particles with long range dipolar interaction is confined by gravity to a flat interface of a hanging water droplet. The particles are observed by video microscopy and the dipolar interaction strength is controlled via an external magnetic field. The system is a m…

Anomalous Hall effect in Y$_2$Fe$_{17-x}$Co$_x$ single crystals

Jolanta Stankiewicz、Konstantin Skokov2009-03-16DIGITAL.CSIC (Spanish National Research Council (CSIC))

We study experimentally the Hall resistivity of Y2Fe17−xCox single crystals with x≤4 for wide temperature and applied magnetic field ranges and for various magnetic field orientations with respect to the easy-magnetization axis. For small x, the anomalous Hall effect (AHE) is very anisotropic in these naturally layere…

Strain Effect in the Problem of Critical Thickness for Ferroelectric Memory

A. M. Bratkovsky、A. P. Levanyuk2009-03-16Bulletin of the American Physical Society

We account for inhomogeneous strains, while calculating two characteristic thicknesses arising in the problem of critical thickness for ferroelectric memory. One of them marks the stability limit of the metastable single-domain state under zero bias voltage with respect to small fluctuations (the spinodal point of the…

Hydrogen in anion vacancies of semiconductors

Mao‐Hua Du、David J. Singh2009-03-16Bulletin of the American Physical Society

Received 16 December 2008; revised manuscript received 8 April 2009; published 6 May 2009Density-functional calculations show that, depending on the anion size, hydrogen in anion vacancies ofvarious II-VI semiconductors can be either twofold or fourfold coordinated and has either amphoteric orshallow donor character.…

Fullerene-based anchoring groups for molecular electronics

Christian Martín、Dapeng Ding、Jakob Kryger Sørensen 等 6 位作者2009-03-16Figshare

We present results on a new fullerene-based anchoring group for molecular electronics. Using lithographic mechanically controllable break junctions in vacuum we have determined the conductance and stability of single-molecule junctions of 1,4-bis(fullero[c]pyrrolidin-1-yl)benzene. The compound can be self-assembled fr…

Effects of polydispersity on the order-disorder transition of diblock copolymer melts

T. M. Beardsley、M. W. Matsen2009-03-16Bulletin of the American Physical Society

The effect of polydispersity on an AB diblock copolymer melt is investigated using lattice-based Monte Carlo simulations. We consider melts of symmetric composition, where the B blocks are monodisperse and the A blocks are polydisperse with a Schultz-Zimm distribution. In agreement with experiment and self-consistent…

Examination of Nonliquidlike Behaviors in Molten Polymer Films

Zichao Yang、Y.J. Wang、Lyudmila Todorova 等 4 位作者2009-03-16OpenAlex

ABSTRACT: Several experiments have shown that polystyrene (PS) films with thicknesses of h ≈ 2RG (where RG is the radius of gyration of the polymer) exhibited nonliquidlike behaviors even in the molten state. By measuring the surface spectrum of PS films subjected to different thermal annealing, we show that similar n…

Waste cleanup efforts underway at the United States Department of Energy's (DOE) Savannah River Site (SRS) in South Carolina, as well as other DOE nuclear sites, have created a need to characterize {sup 79}Se in radioactive waste inventories. Successful analysis of {sup 79}Se in high activity waste matrices is challen…
