Effect of magnetic field on quasiparticle branches of intrinsic Josephson junctions with ferromagnetic layer
The interlayer tunneling spectroscopy has been performed on micron-sized mesa arrays of HgBr2 intercalated superconducting Bi2212 single crystals. A ferromagnetic multilayer (Au/Co/Au) is deposited on top of the mesas. The ...
Investigation of the tunneling spectra in HgBr2-intercalated Bi-2212 single crystals below and above Tc
Interlayer tunneling spectroscopy measurements were performed on mesa arrays of Bi-2212 single crystals, intercalated with HgBr2. Tunneling conductances were obtained over a wide temperature range to examine the spectral ...
Large energy gaps in Ca C6 from tunneling spectroscopy: Possible evidence of strong-coupling superconductivity
(American Physical Society, 2007-12)
Tunneling in Ca C6 crystals reproducibly reveals superconducting gaps Δ of 2.3±0.2 meV that are ∼40% larger than reported earlier. In an isotropic s -wave scenario, that puts Ca C6 into the class of very strongly coupled ...
