Observation of the developed Cu-spin correlation in the Bi-2201 high-Tc superconductor using muon spin relaxation
Observation of the developed Cu-spin correlation muon spin relaxation
2010/11/24
A systematic muon-spin-relaxation study in Bi-2201 high-Tc cuprates has revealed for the first
time that the Cu-spin correlation (CSC) is developed at low temperatures below 2 K in a wide
range of h...
Direct observation of band-gap closure for a semiconducting carbon nanotube in a large parallel magnetic field
Direct observation of band-gap closure semiconducting carbon nanotube large parallel magnetic field
2010/11/23
We have investigated the magnetoconductance of semiconducting carbon nanotubes (CNTs) in
pulsed, parallel magnetic elds up to 60 T, and report the direct observation of the predicted band-gap closur...
Observation of exchange Coulomb interactions in the quantum Hall state at nu=3
exchange Coulomb interactions quantum Hall state
2010/11/19
Coulomb exchange interactions of electrons in the = 3 quantum Hall state are determined from
two inter-Landau level spin-flip excitations measured by resonant inelastic light scattering. The two co...
First Observation of Quantum Oscillations in the Ferromagnetic Superconductor UCoGe
Quantum Oscillations Ferromagnetic Superconductor UCoGe
2010/11/24
We succeeded in growing high quality single crystals of the ferromagnetic superconductor
UCoGe and measured the magnetoresistance at fields up to 34T. The Shubnikov-de Haas
signal was observed for t...
