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…
New excitations in bcc He - an inelastic neutron scattering study
O. Pelleg, J. Bossy, E. Farhi +3
We report neutron scattering measurements on bcc solid % He. We studied the phonon branches and the recently discovered ''optic-like'' branch along the main crystalline direc…
Path-integral Monte Carlo study of phonons in the bcc phase of Helium-3
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-3 in the bcc phase at a finite temperature of T = 1.6 K and a…
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…
