Interplay between the orbital quantization and Pauli effect in a charge-density-wave organic conductor
M. Kartsovnik, D. Andres, P. Grigoriev +2
The interlayer magnetoresistance of the low-dimensional organic metal α-(BEDT-TTF)2KHg(SCN)4 under pressure shows features which are likely associated with theoretically predicted…
Massive Spin Collective Mode in Quantum Hall Ferromagnet
T. Maniv, Yu. A. Bychkov, I. D. Vagner
It is shown that the collective spin rotation of a single Skyrmion in quantum Hall ferromagnet can be regarded as precession of the entire spin texture in the external magnetic fie…
Microwave radiation induced magneto-oscillations in the longitudinal and transverse resistance of a two dimensional electron gas
S. A. Studenikin, M. Potemski, P. T. Coleridge +2
We confirm the existance of magneto-resistance oscillations in a microwave-irradiated two-dimensional electron gas, first reported in a series of papers by Zhudov et al. and Mani e…
Magnetization of Nuclear-Spin-Polarization-Induced Quantum Ring
S. N. Shevchenko, Yu. V. Pershin, I. D. Vagner
Properties of a Nuclear-Spin-Polarization-Induced Quantum Ring (NSPI QR) are studied theoretically. In the proposed system a local nuclear spin polarization creates an effective hy…
Magneto-optical evidence for a gapped Fermi surface in underdoped YBa2Cu3O6+x
L. B. Rigal, D. C. Schmadel, H. D. Drew +5
The infrared (900-1100 cm-1) Faraday rotation and circular dichroism are measured in the normal state of underdoped High Tc superconductors and used to study the magneto-transport.…
Longitudinal conductivity in Si/SiGe heterostructure at integer filling factors
I. Shlimak, V. Ginodman, M. Levin +4
We have investigated temperature dependence of the longitudinal conductivity at integer filling factors for Si/SiGe heterostructure in the quantum Hall effect regime…
Lift of degeneracy of Landau levels of 2D electron gas by point-like impurities
A. M. Dyugaev, P. D. Grigoriev, Yu. N. Ovchinnikov
We study the density of states of two-dimensional electron gas in magnetic field with scattering on point-like impurities that are uniformly distributed along the sample. We show t…
High-field magnetization study of the S = 1/2 antiferromagnetic Heisenberg chain [PM Cu(NO)(HO)] with a field-induced gap
A. U. B. Wolter, H. Rakoto, M. Costes +8
We present a high-field magnetization study of the = 1/2 antiferromagnetic Heisenberg chain [PM Cu(NO)(HO)]. For this material, as result of the Dzyaloshins…
Collective character of spin excitations in a system of Mn spins coupled to a two-dimensional electron gas
F. J. Teran, M. Potemski, D. K. Maude +7
We have studied the low energy spin excitations in n-type CdMnTe based dilute magnetic semiconductor quantum wells. For magnetic fields for which the energies for the excitation of…
Magnetic properties of GaMnAs single layers and GaInMnAs superlattices investigated at low temperature and high magnetic field
C. Hernandez, F. Terki, S. Charar +4
Magnetotransport properties of GaMnAs single layers and InGaMnAs/InGaAs superlattice structures were investigated at temperatures from 4 K to 300 K and magnetic fields up to 23 T t…
Phase separation effects in charge-ordered Pr0.5Ca0.5MnO3 thin film
S. de Brion, G. Storch, G. Chouteau +3
Compressed Pr0.5Ca0.5MnO3 films (250nm) deposited on LaAlO3 have been studied by Electron Spin Resonance technique under high frequency and high magnetic field. We show evidences f…

Yu. Krupko, L. Smrcka, P. Vasek +3
We have investigated experimentally the magnetoresistance of strongly asymmetric double-wells. The structures were prepared by inserting a thin AlGaAs barrier into…
Vortex states in 2D superconductor at high magnetic field in a periodic pinning potential
V. Zhuravlev, T. Maniv
The effect of a periodic pinning array on the vortex state in a 2D superconductor at low temperatures is studied within the framework of the Ginzburg-Landau approach. It is shown t…

S. S. Murzin, A. G. M. Jansen, I. Claus
Oscillatory variations of the diagonal () and Hall () magnetoconductances are discussed in view of topological scaling effects giving rise to the quantum Hall effec…
Electronic structure of nuclear-spin-polarization-induced quantum dots
Yu. V. Pershin
We study a system in which electrons in a two-dimensional electron gas are confined by a nonhomogeneous nuclear spin polarization. The system consists of a heterostructure that has…
