Topology and spin dynamics in magnetic molecules
S. Carretta, P. Santini, G. Amoretti +6
We investigate the role of topology and distortions in the quantum dynamics of magnetic molecules, using a cyclic spin system as reference. We consider three variants of antiferrom…
From antiferromagnetism to superconductivity in Fe 1+y(Te1-x,Sex) (0 < x < 0.20): a neutron powder diffraction analysis
A. Martinelli, A. Palenzona, M. Tropeano +6
The nuclear and magnetic structure of Fe1+y(Te1-x,Sex) (0 < x < 0.20) compounds was analyzed between 2 K and 300 K by means of Rietveld refinement of neutron powder diffraction dat…
Inhomogeneous magnetism in the doped kagome lattice of LaCuO2.66
M. -H. Julien, V. Simonet, B. Canals +6
The hole-doped kagome lattice of Cu2+ ions in LaCuO2.66 was investigated by nuclear quadrupole resonance (NQR), electron spin resonance (ESR), electrical resistivity, bulk magnetiz…
Superconducting energy gap in : Temperature dependence
F. Szabo, P. Samuely, N. L. Bobrov +3
The superconducting energy gap of has been measured by tunneling. Despite the fact that the sample was macroscopically single phase with very sharp supercond…
Landau-Zener transition in a continuously measured single-molecule spin transistor
F. Troiani, C. Godfrin, S. Thiele +5
We monitor the Landau-Zener dynamics of a single-ion magnet in a spin-transistor geometry. For increasing field-sweep rates, the spin reversal probability shows increasing deviatio…
Hysteresis loops of the magnetoconductance in graphene devices
A. Candini, C. Alvino, W. Wernsdorfer +1
We report very low temperature magnetoconductance DeltaG measurements on graphene devices with the magnetic field H applied parallel to the carbon sheet. The DeltaG(H) signal depen…
