A 350 mK, 9 T scanning tunneling microscope for the study of superconducting thin films and single crystals
Anand Kamlapure, Garima Saraswat, Somesh Chandra Ganguli +3
We report the construction and performance of a low temperature, high field scanning tunneling microscope (STM) operating down to 350mK and in magnetic fields up to 9T, with thin f…
Anomalous bias dependence of tunnel magnetoresistance in a magnetic tunnel junction
Soumik Mukhopadhyay, I. Das, S. P. Pai +1
We have fabricated a spin-polarized tunneling device based on half metallic manganites incorporating as insulating barrier. An anomalous bias dependence of tunnel…
Self Injection length in La0.7 Ca0.3 Mno3-YBa 2Cu3O7-d ferromagnet- superconductor multi layer thin films
S. P. Pai, S. Wanchoo, S. C. Purandare +4
We have carried out extensive studies on the self-injection problem in barrierless heterojunctions between La0.7Ca0.3MnO3 (LCMO) and YBa2Cu3O7-d (YBCO). The heterojunctions were gr…
Is there a vortex-glass transition in high-temperature superconductors?
D. R. Strachan, M. C. Sullivan, P. Fournier +3
We show that DC voltage versus current measurements of a YBCO micro-bridge in a magnetic field can be collapsed onto scaling functions proposed by Fisher, Fisher, and Huse, as is w…
