Bistability of vortex core dynamics in a single perpendicularly magnetized nano-disk
Grégoire De Loubens, A. Riegler, B. Pigeau +10
Microwave spectroscopy of individual vortex-state magnetic nano-disks in a perpendicular bias magnetic field, , is performed using a magnetic resonance force microscope (MRFM).…
Two insulating phases in compressed Pr1-xCaxMnO3 thin films
M. Filippi, W. Prellier, P. Auban-Senzier +1
The temperature dependent resistivity of two Pr1-xCaxMnO3 (x=0.5 and 0.4) thin films grown on LaAlO3 has been studied as a function of hydrostatic pressure (up to 2.5 GPa) and magn…
Phase transition and anomalous electronic behavior in layered dichalcogenide CuS (covellite) probed by NQR
R. R. Gainov, A. V. Dooglav, I. N. Penkov +4
Nuclear quadrupole resonance (NQR) on copper nuclei has been applied for studies of the electronic properties of quasi-two-dimensional low-temperature superconductor CuS (covellite…
Ab initio study of bilateral doping within the MoS2-NbS2 system
Viktoriya V. Ivanovskaya, Alberto Zobelli, Alexandre Gloter +3
We present a systematic study on the stability and the structural and electronic properties of mixed molybdenum-niobium disulphides. Using density functional theory we investigate…
Shaping single walled nanotubes
Alberto Zobelli, Alexandre Gloter, Chris P. Ewels +1
We show that electron irradiation in a dedicated scanning transmission microscope can be used as a nano-electron-lithography technique allowing the controlled reshaping of single w…
Orbital contribution to the magnetic properties of iron as a function of dimensionality
Marie-Catherine Desjonquères, Cyrille Barreteau, Gabriel Autes +1
The orbital contribution to the magnetic properties of Fe in systems of decreasing dimensionality (bulk, surfaces, wire and free clusters) is investigated using a tight-binding ham…
