The influence of boundaries on high pressure melting experiments
V. Sorkin, E. Polturak, Joan Adler
At low pressure, free surfaces play a crucial role in the melting transition. Under pressure, the surface of the sample is acted upon by some pressure transmitting medium. To exami…
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…
Observation of Macroscopic Structural Fluctuations in bcc Solid 4He
O. Pelleg, M. Shay, S. G. Lipson +6
We report neutron diffraction studies of low density bcc and hcp solid 4He. In the bcc phase, we observed a continuous dynamical behaviour involving macroscopic structural changes…
Path Integral Monte Carlo study of phonons in the bcc phase of He
V. Sorkin, E. Polturak, Joan Adler
Using Path Integral Monte Carlo and the Maximum Entropy method, we calculate the dynamic structure factor of solid He in the bcc phase at a finite temperature of T = 1.6 K and…
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…
