Reversible transitions in high- cuprates based point contacts
L. F. Rybalchenko, N. L. Bobrov, V. V. Fisun +3
The influence of electric felds and currents has been investigated in the high- superconductors and using a point-contact geometry with as the counte…
Magnetoquantum oscillations in the resistance of metallic point contacts: Influence of nonequilibrium phonons
N. L. Bobrov, J. A. Kokkedee, N. N. Gribov +3
The amplitude of magnetoresistance quantum oscillations of Al and Be point contacts in a magnetic field parallel to the contact axis has been studied as a function of voltage appli…
Anisotropy of the Upper Critical Field and Critical Current in Single Crystal MgB
L. Lyard, P. Samuely, P. Szabo +15
We report on specific heat, high magnetic field transport and susceptibility measurements on magnesium diboride single crystals. The upper critical field for magnetic…
Universal flow diagram for the magnetoconductance in disordered GaAs layers
S. S. Murzin, M. Weiss, A. G. M. Jansen +1
The temperature driven flow lines of the diagonal and Hall magnetoconductance data (G_{xx},G_{xy}) are studied in heavily Si-doped, disordered GaAs layers with different thicknesse…
Magnetotransport and the upper critical magnetic field in MgB2
P. Szabo, P. Samuely, A. G. M. Jansen +4
Magnetotransport measurements are presented on polycrystalline MgB2 samples. The resistive upper critical magnetic field reveals a temperature dependence with a positive curvature…
Phonon-assisted tunneling in the quantum regime of Mn12-ac
I. Chiorescu, R. Giraud, A. G. M. Jansen +2
Longitudinal or transverse magnetic fields applied on a crystal of Mn12-ac allows to observe independent tunnel transitions between m=-S+p and m=S-n-p (n=6-10, p=0-2 in longitudina…
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…
Quantum Hall Effect induced by electron-electron interaction in disordered GaAs layers with 3D spectrum
S. S. Murzin, I. Claus, A. G. M. Jansen +3
It is shown that the observed Quantum Hall Effect in epitaxial layers of heavily doped n-type GaAs with thickness (50-140 nm) larger the mean free path of the conduction electrons…
