Fine tuning epitaxial strain in ferroelectrics: PbxSr(1-x)TiO3 on DyScO3
ferroelectrics strain thin films phase diagram phase boundaries
2010/11/24
Epitaxial strain can be efficiently used to modify the properties of ferroelectric thin films. From the experi-mental viewpoint, the challenge is to fine-tune the magnitude of the strain. We illustrat...
Transient shear banding in entangled polymers: a study using the Rolie-Poly model
Transient shear banding Rolie-Poly model
2010/11/24
Spatially inhomogeneous shear flow occurs in entangled polymer solutions, both as steady state shear banding and transiently after a large step strain or during start up to a steady uniform shear rate...
Orientation dependence of the elastic instability on strained SiGe films
Orientation dependence elastic instability strained SiGe films
2010/11/23
At low strain, SiGe films on Si substrates undergo a continuous nucleationless morphological evolution known as the Asaro-Tiller-Grinfeld instability. We demonstrate experimentally that this instabili...
Lattice QCD at the physical point: light quark masses
Lattice QCD physical point light quark masses
2011/1/14
Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...
Nanopattern-stimulated superconductor-insulator transition in thin TiN films
Nanopattern-stimulated superconductor-insulator transition thin TiN films
2010/11/18
We present the results of the comparative study of the influence of disorder on transport prop-
erties in continuous and nanoperforated TiN films. We show that nanopatterning turns a thin
TiN film i...
We report resonant ultrasound spectroscopy (RUS), dilatometry/magnetostriction, magnetotransport,magnetization, speci c-heat, and 119Sn Mossbauer spectroscopy measurements on SnTe and Sn0:995Cr0:005T...
Magnetic microstructure and magnetotransport in Co2FeAl Heusler compound thin films
Magnetic microstructure agnetotransport Co2FeAl Heusler compound thin films
2010/11/18
We correlate simultaneously recorded magnetotransport and spatially resolved magneto optical Kerr effect (MOKE) data in Co2FeAl Heusler compound thin films micropatterned into Hall bars. Room temperat...
Local electronic structure of Fe$^{2+}$ impurities in MgO thin films: Temperature-dependent soft x-ray absorption spectroscopy study
Local electronic structure of Fe$^{2+}$ impurities Temperature-dependent soft x-ray absorption spectroscopy study
2010/11/18
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state.The fi...

Element specific characterization heterogeneous magnetism
2010/11/18
We employ x-ray spectroscopy to characterize the distribution and magnetism of particular alloy
constituents in (Ga,Fe)N films grown by metal organic vapor phase epitaxy. Furthermore, photo-
electro...
Elastic and electronic properties of hexagonal rhenium sub-nitrides Re3N and Re2N in comparison with hcp-Re and wurtzite-like rhenium mononitride ReN
Elastic electronic properties Re2N in comparison
2010/11/23
Very recently, two new hexagonal rhenium sub-nitrides Re3N and Re2N, which belong to a rather rare group of known metal-rich (M/N > 1) nitrides of heavy 4d,5d metals, have been successfully synthesize...
Forces and fluctuations in planar, spherical and tubular membranes
Forces luctuations spherical tubular membranes
2010/11/18
Lipid membranes constitute very particular materials: on the one hand, they break very easily under microscopical stretching; on the other hand, they are extremely flexible, presenting deformations ev...

Experimental observation of superfluidity in a microscopic cluster, M : (4He)x, of a
molecule (M) and x number of 4He atoms (with x ranging from 1 to many) is qualitatively
analyzed. It concludes th...

2010/11/23
Using field theoretic approach, we study equilibrium shape deformation of a vesicle
induced by the presence of enclosed flexible polymers, which is a simple model of drug delivery

Two-hadron correlations in the Color Glass Condensate formalism
Two-hadron correlations Color Glass Condensate formalism
2011/1/7
Two-hadron correlations are a sensitive probe of the dynamics of gluon saturation and the Color Glass Condensate formalism where the degrees of freedom are Wilson lines of the gluon field.
Tuning macro-twinned domain sizes and the b-variants content of the adaptive 14-modulated martensite in epitaxial Ni-Mn-Ga films by co-sputtering
