3D-melting features of the irreversibility line in overdoped BiSrCuO at ultra-low temperature and high magnetic field
A. Morello, A. G. M. Jansen, R. S. Gonnelli +1
We have measured the irreversible magnetization of an overdoped BiSrCuO single crystal up to B=28 T and down to T=60 mK, and extracted the irreversibility line $B_{\rm…
The Addition Spectrum of a Lateral Dot from Coulomb and Spin Blockade Spectroscopy
M. Ciorga, A. S. Sachrajda, P. Hawrylak +5
Transport measurements are presented on a class of electrostatically defined lateral dots within a high mobility two dimensional electron gas (2DEG). The new design allows Coulomb…
Metal-Insulator oscillations in a Two-dimensional Electron-Hole system
R. J. Nicholas, K. Takashina, M. Lakrimi +6
The electrical transport properties of a bipolar InAs/GaSb system have been studied in magnetic field. The resistivity oscillates between insulating and metallic behaviour while th…
Cu NMR evidence for enhanced antiferromagnetic correlations around Zn impurities in YBa2Cu3O6.7
M. -H. Julien, T. Feher, M. Horvatic +5
Doping the high-Tc superconductor YBa2Cu3O6.7 with 1.5 % of non-magnetic Zn impurities in CuO2 planes is shown to produce a considerable broadening of 63Cu NMR spectra, as well as…
Magnetic Field Dependent Tunneling in Glasses
P. Strehlow, M. Wohlfahrt, A. G. M. Janssen +4
We report on experiments giving evidence for quantum effects of electromagnetic flux in barium alumosilicate glass. In contrast to expectation, below 100 mK the dielectric response…
Low Dimensional Correlated Systems: Cugeo_3 and Nav_2O_5
P. H. M. Van Loosdrecht, J. Zeman, G. Martinez +3
Some of the properties of the low-dimensional electronically correlated materials \cgo and \nvo are discussed. The emphasis lies on recent results obtained using Raman scattering a…
NMR Determination of 2D Electron Spin Polarization at
S. Melinte, N. Freytag, M. Horvatic +4
Using a `standard' NMR spin-echo technique we determined the spin polarization of two-dimensional electrons, confined to GaAs quantum wells, from the hyperfine shift of Ga nuclei i…
The irreversibility line of overdoped Bi_{2+x}Sr_{2-(x+y)}Cu_{1+y}O_{6 +- delta} at ultra-low temperatures and high magnetic fields
A. Morello, A. G. M. Jansen, R. S. Gonnelli +1
The irreversible magnetization of the layered high-T_{c} superconductor Bi_{2+x}Sr_{2-(x+y)}Cu_{1+y}O_{6 +- delta} (Bi-2201) has been measured by means of a capacitive torquemeter…
Proton NMR for Measuring Quantum-Level Crossing in the Magnetic Molecular Ring Fe10
M. -H. Julien, Z. H. Jang, A. Lascialfari +4
The proton nuclear spin-lattice relaxation rate 1/T1 has been measured as a function of temperature and magnetic field (up to 15 T) in the molecular magnetic ring Fe10. Striking en…
Charge Segregation, Cluster Spin-Glass and Superconductivity in La1.94Sr0.06CuO4
M. -H. Julien, F. Borsa, P. Carretta +3
A 63Cu and 139La NMR/NQR study of superconducting (Tc=7 K) La1.94Sr0.06CuO4 single crystal is reported. Coexistence of spin-glass and superconducting phases is found below ~5 K fro…
Y NMR imaging of the staggered magnetization in doped Haldane chain Y(2)BaNi(1-x)Mg(x)O(5)
F. Tedoldi, R. Santachiara, M. Horvatic
We present a static, model-independent, experimental determination of the spin-spin correlation length ξin a quantum spin system. This is achieved in doped Haldane (i.e., S=1 Heise…
Soliton Lattices in the Incommensurate Spin-Peierls Phase: Local Distortions and Magnetizations
Goetz S. Uhrig, Friedhelm Schoenfeld, Jean-Paul Boucher +1
It is shown that nonadiabatic fluctuations of the soliton lattice in the spin-Peierls system CuGeO_3 lead to an important reduction of the NMR line widths. These fluctuations are t…
Optics of a Faraday-active Mie Sphere
D. Lacoste, B. A. van Tiggelen
We present an exact calculation for the scattering of light from a single sphere made of a Faraday-active material, into first order of the external magnetic field. When the size o…
Topological defects and Goldstone excitations in domain walls between ferromagnetic quantum Hall effect liquids
Vladimir I. Fal'ko, S. V. Iordanskii
It is shown that the low-energy spectrum of a ferromagnetic quantum Hall effect liquid in a system with a multi-domain structure generated by an inhomogeneous bare Zeeman splitting…
