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…
Observation of a New Mechanism of Spontaneous Generation of Magnetic Flux in a Superconductor
A. Maniv, E. Polturak, G. Koren +6
We report the discovery of a new mechanism of spontaneous generation of a magnetic flux in a superconductor cooled through . The sign of the spontaneous flux changes randomly…
Observation of McMillan-Rowell like oscillations in underdoped YBCO junctions oriented along the node of the d-wave order parameter
L. Shkedy, P. Aronov, G. Koren +1
Dynamic resistance spectra of ramp junctions made of underdoped YBCO electrodes and Ga-doped YBCO barrier are reported. Series of equidistant peaks were observed in these spectra i…
