Planar SFS Josephson Junctions Made by Focused Ion Beam Etching
V. M. Krasnov, O. Ericsson, S. Intiso +4
Superconductor-Ferromagnet-Superconductor (S-F-S) Josephson junctions were fabricated by making a narrow cut through a S-F double layer using direct writing by Focused Ion Beam (FI…
In-situ measurement of self-heating in intrinsic tunnelling spectroscopy
V. M. Krasnov, M. Sandberg, I. Zogaj
Using advanced sample engineering we performed simultaneous measurement of intrinsic (interlayer) tunnelling characteristics and in-situ monitoring of temperature in small Bi-2212…
Intrinsic tunneling spectroscopy: A look from the inside at HTSC
V. M. Krasnov
Layered structure of Bi-2212 high superconductor (HTSC), provides a unique opportunity to probe quasiparticle density of states inside a bulk single crystal by means of intri…
Intrinsic tunneling spectroscopy in small Bi2212 mesas
V. M. Krasnov, A. Yurgens, D. Winkler +1
We present intrinsic tunneling spectroscopy measurements on small BiSrCaCuO mesas. The tunnel conductance curves show both sharp peaks at the superconducting ga…
