Superconductivity in the crystallogenide LaFeSiO with squeezed FeSi layers
M. F. Hansen, J. -B. Vaney, C. Lepoittevin +10
Pnictogens and chalcogens are both viable anions for promoting Fe-based superconductivity and intense research activity in the related families has established systematic correlati…
Anomalous magnetic field dependence of the thermodynamic transition line in the isotropic superconductor (K,Ba)Bi03
S. Blanchard, T. Klein, J. Marcus +6
Thermodynamic (specific heat, reversible magnetization, tunneling spectroscopy) and transport measurements have been performed on high quality (K,Ba)BiO single crystals. The te…
Enhancement of Andreev reflection by spin polarization in out-of-equilibrium ferromagnet-superconductor junctions
O. Bourgeois, P. Gandit, J. Lesueur +4
We report on transport measurements on Nb/Al/Gd/Al/Nb junctions.Bulk Gadolinium is a weakly polarized ferromagnet (5-7%), and is present in the junction in granular form (superpara…
Magnetic and structural properties of the iron silicide superconductor LaFeSiH
M. F. Hansen, S. Layek, J. -B. Vaney +20
The magnetic and structural properties of the recently discovered pnictogen/chalcogen-free superconductor LaFeSiH (~K) have been investigated by Fe synchrotron…
Spin-Peierls transition with strong structural fluctuations in the vanadium oxide VOSbO
V. A. Pashchenko, A. Sulpice, F. Mila +3
We report on the magnetic susceptibility and electron spin resonance measurements on polycrystalline samples of the vanadium oxide VOSbO, a quasi-one dimensional S=1/2…
Experimental study of the competition between Kondo and RKKY interactions for Mn spins in a model alloy system
J. J. Prejean, E. Lhotel, A. Sulpice +1
The quasicrystal Al-Pd-Mn is a model system for an experimental study of the competition between Ruderman-Kittel-Kasuya-Yoshida (RKKY) and Kondo interactions. First, specific of su…
