Measurement of the vortex mass in a superconducting film
Daniel Golubchik, Emil Polturak, Gad Koren
We have combined high resolution magneto-optical imaging with an ultra-fast heating/cooling technique to measure the movement of individual vortices in a superconducting film. The…
Correlations beyond the horizon
Daniel Golubchik, Emil Polturak, Gad Koren
We have imaged spontaneously created arrays of vortices (magnetic flux quanta), generated in a superconducting film quenched through its transition temperature at rates around $10^…
A study of the ferromagnetic transition of in nanometer thick bilayers with , , Au and Cr: Signature of injected carriers in the pseudogap regime
G. Aharonovich, G. Koren, E. Polturak
The hypothesis regarding the existence of uncorrelated pre-formed pairs in the pseudogap regime of superconducting is tested experimentally using bilayers of $YBa_2C…
Quantum vortex tunneling in thin films
G. Koren, Y. Mor, A. Auerbach +1
Cuprate films offer a unique opportunity to observe vortex tunneling effects, due to their unusually low superfluid density and short coherence length. Here, we measure the magneto…
Experimental search for anisotropic flux flow resistivity in the a-b plane of optimally doped epitaxial thin films of YBCO
G. Koren, P. Aronov, E. Polturak
Transport measurements along the node and anti-node directions in the a-b plane of optimally doped and epitaxial thin films of YBCO are reported. Low bias magnetoresistance measure…
Magnetoresistance of Junctions made of Underdoped YBCO Separated by a Ga-doped YBCO Barrier
L. Shkedy, G. Koren, E. Polturak
We report magnetoresistance measurements of ramp type superconductor-normal-superconductor (SNS) junctions. The junctions consist of underdoped (YBCO) electrodes…
