Clocking the Melting Transition of Charge and Lattice Order in 1T-TaS2 with Ultrafast Extreme-Ultraviolet Angle-Resolved Photoemission Spectroscopy

We use time- and angle-resolved photoemission spectroscopy with sub-30-fs extreme-ultraviolet pulses to map the time- and momentum-dependent electronic structure of photoexcited 1T-TaS2. This compound is a two-dimensional Mott insulator with charge-density ...

Broadband inversion for MAS NMR with single-sideband-selective adiabatic pulses

David Lyndon Emsley, Philip John Grandinetti

We explain how and under which conditions it is possible to obtain an efficient inversion of an entire sideband family of several hundred kHz using low-power, sideband-selective adiabatic pulses, and we illustrate with some experimental results how this fr ...

Position of defects with respect to domain walls in Fe[sup 3+]-doped Pb[Zr[sub 0.52]Ti[sub 0.48]]O[sub 3] piezoelectric ceramics

Dragan Damjanovic, Li Jin

The position of (Fe-Zr',(Ti)-V-O(center dot center dot))(center dot) defect complexes in Pb[Zr0.52Ti0.48]O-3 (PZT) piezoelectric ceramics was investigated by means of electron paramagnetic resonance (EPR) spectroscopy. The method of analysis pursued to obt ...

Structural influence on the Rashba-type spin splitting in surface alloys

Klaus Kern, Jan Hugo Dil, Isabella Gierz

The Bi/Ag(111), Pb/Ag(111), and Sb/Ag(111) surface alloys exhibit a two-dimensional band structure with a strongly enhanced Rashba-type spin splitting, which is in part attributed to the structural asymmetry resulting from an outward relaxation of the allo ...

Large polaron formation induced by Rashba spin-orbit coupling

Claudio Grimaldi

Here the electron-phonon Holstein model with Rashba spin-orbit interaction is studied for a two-dimensional square lattice in the adiabatic limit. It is demonstrated that a delocalized electron at zero spin-orbit coupling localizes into a large polaron sta ...

Spectroscopic Studies on Semiconducting Interfaces with Giant Spin Splitting

Emmanouil Frantzeskakis

The application of an external magnetic field can lift the spin degeneracy of electronic states through its interaction with the electronic magnetic moment. A closely-related phenomenon is the Rashba-Bychkov (RB) effect where symmetry breaking at surfaces ...

Origin of the ESR spectrum in the Prussian blue analog RbMn[Fe(CN)(6)]center dot H2O

László Forró

We present an electron spin resonance (ESR) study at excitation frequencies of 9.4 and 222.4 GHz of powders and single crystals of a Prussian blue analog (PBA), RbMn[Fe(CN)(6)]center dot H2O in which Fe and Mn undergoes a charge-transfer transition between ...

Observations of Pauli paramagnetic effects on the flux line lattice in CeCoIn5

Sandrine Gerber, Joël Mesot, Jonathan White, Pratyush Das

From small-angle neutron scattering studies of the flux line lattice (FLL) in CeCoIn5, with magnetic field applied parallel to the crystal c-axis, we obtain the field and temperature dependence of the FLL form factor (FF), which is a measure of the spatial ...

Size dependence of the magnetic response of graphite oxide and graphene flakes - an electron spin resonance study

László Forró, Arnaud Magrez, Andrzej Sienkiewicz, Luka Ciric, Rita Smajda

We employed electron spin resonance (ESR) technique in the investigation of a series of graphene flakes with different size distributions. Graphene oxide (GO) samples with three distinct size distributions were prepared by the Brodie method. Large flakes o ...

Magnetic anisotropy of Fe and Co adatoms and Fe clusters magnetically decoupled from Ni_{3}Al(111) by an alumina bilayer

Harald Brune, Stefano Rusponi, Markus Etzkorn, Anne Lehnert

The magnetic properties of individual Fe and Co atoms as well as of small Fe clusters adsorbed on two atomic layers of Al2O3 grown on Ni3Al(111) have been investigated by x-ray absorption spectroscopy and x-ray magnetic circular dichroism. We find ratios o ...
