Increased superconducting transition temperature of a niobium thin-film proximity-coupled to gold nanoparticles using linking organic molecules
Eran Katzir, Shira Yochelis, Felix Zeides +8
The superconducting critical temperature, TC, of thin Nb films is significantly modified when gold nanoparticles (NPs) are chemically linked to the Nb film, with a consistent enhan…
Weak links and phase slip centers in superconducting MgB2 wires
Maya Bar-Sadan, Gregory Leitus, Shimon Reich
MgB2 superconducting wires were produced by the Mg diffusion method. Scanning electron microscopy (SEM), optical microscopy, dispersive x-ray analysis (EDS) and XRD diffraction wer…
Measurement of corrosion content of archaeological lead artifacts by their Meissner response in the superconducting state; a new dating method
S. Reich, G. Leitus, S. Shalev
Meissner fraction in the superconducting state of lead archaeological artifacts is used to evaluate the mass of the uncorroded metal in the sample. Knowing the total mass of the sa…
Magnetization of small lead particles
S. Reich, G. Leitus, R. Popovitz-Biro +1
The magnetization of an ensemble of isolated lead grains of sizes ranging from below 6 nm to 1000 nm is measured. A sharp disappearance of Meissner effect with lowering of the grai…
On the Magnetism of the Normal State in MgB2
S. Reich, G. Leitus, I. Felner
The experimentally observed ferromagnetism in MgB2 in the normal state is attributed to micro phase separated inclusions of iron. This magnetic character is also observed when the…
