London penetration depth of electron-irradiated Ba1-xKxFe2As2 single-crystals
P. Gierlowski, B. Cury Camargo, I. Abaloszewa +5
We have characterized an electron-irradiated Ba1-xKxFe2As2 (x = 0.53) single-crystal using two different experimental techniques: magneto-optic measurements and microwave measureme…
Magnetization of BiSrCaCuO micrometer thin ring and its depinning line
B. Semenenko, B. C. Camargo, A. Setzer +3
We demonstrate a geometrical effect on the depinning line (DL) of the flux line lattice of the BiSrCaCuO high-T superconductor (HTSC) micrometer ring.…
Macroscopic-ranged proximity effect in graphite
Bruno Cury Camargo, Piotr Gierlowski, Marek Kuzmiak +4
We report the observation of proximity effect in measurements performed on highly oriented pyrolitic graphite (HOPG) samples when electrical current is injected through the superco…
Unstable and elusive superconductors
Yakov Kopelevich, Robson R. da Silva, Bruno C. Camargo
We briefly review earlier and report original experimental results in the context of metastable or possible superconducting materials. We show that applied electric field induces c…
Extraordinary magnetoresistance in graphite: experimental evidence for the time-reversal symmetry breaking
Y. Kopelevich, R. R. da Silva, A. S. Alexandrov
The ordinary magnetoresistance (MR) of doped semiconductors is positive and quadratic in a low magnetic field, B, as it should be in the framework of the Boltzmann kinetic theory o…
