Thermodynamic evidence for the Bose glass transition in twinned YBaCuO crystals
D. J. Pérez-Morelo, E. Osquiguil, A. B. Kolton +4
We used a micromechanical torsional oscillator to measure the magnetic response of a twinned YBaCuO single crystal disk near the Bose glass transition. We observe a…
Barkhausen-type noise in the resistance of antiferromagnetic Cr thin films
L. Tosi, E. Osquiguil, E. E. Kaul +1
We present an experimental study of the changes generated on the electrical resistance of epitaxial Cr thin films by the transformation of quantized spin density wave domain…
Effects of spin density wave quantization on the electrical transport in epitaxial Cr thin films
E. Osquiguil, E. E. Kaul, L. Tosi +1
We present measurements of the electrical resistivity, , in epitaxial Cr films of different thicknesses grown on MgO (100) substrates, as a function of temperature, . The $ρ(…
Doping-Dependent Nonlinear Meissner Effect and Spontaneous Currents in High-Tc Superconductors
Sheng-Chiang Lee, Mathew Sullivan, Gregory R. Ruchti +4
We measure the local harmonic generation from superconducting thin films at microwave frequencies to investigate the intrinsic nonlinear Meissner effect near Tc in zero magnetic fi…
Magneto-optical evidence for a gapped Fermi surface in underdoped YBa2Cu3O6+x
L. B. Rigal, D. C. Schmadel, H. D. Drew +5
The infrared (900-1100 cm-1) Faraday rotation and circular dichroism are measured in the normal state of underdoped High Tc superconductors and used to study the magneto-transport.…
Elastic-to-plastic crossover below the peak effect in the vortex solid of YBa2Cu3O7 single crystals
Sergio O. Valenzuela, Boris Maiorov, Eduardo Osquiguil +1
We report on transport and ac susceptibility studies below the peak effect in twinned YBa2Cu3O7 single crystals. We find that disorder generated at the peak effect can be partially…
