Suppression of the structural phase transition and lattice softening in slightly underdoped Ba(1-x)K(x)Fe2As2 with electronic phase separation
D. S. Inosov, A. Leineweber, Xiaoping Yang +12
We present x-ray powder diffraction (XRPD) and neutron diffraction measurements on the slightly underdoped iron pnictide superconductor Ba(1-x)K(x)Fe2As2, Tc = 32K. Below the magne…
Field-induced soft-mode quantum phase transition in LaSrCuO
J. Chang, N. B. Christensen, Ch. Niedermayer +13
Inelastic neutron-scattering experiments on the high-temperature superconductor LaSrCuO reveal a magnetic excitation gap that decreases continuously u…
Electronic phase separation in the slightly underdoped iron pnictide superconductor Ba(1-x)K(x)Fe(2)As(2)
J. T. Park, D. S. Inosov, Ch. Niedermayer +14
Here we present a combined study of the slightly underdoped novel pnictide superconductor Ba(1-x)K(x)Fe(2)As(2) by means of X-ray powder diffraction, neutron scattering, muon spin…
High Q Cavity Induced Fluxon Bunching in Inductively Coupled Josephson Junctions
Søren Madsen, Niels Grønbech-Jensen, Niels Falsig Pedersen +1
We consider fluxon dynamics in a stack of inductively coupled long Josephson junctions connected capacitively to a common resonant cavity at one of the boundaries. We study, throug…
Novel Regime of Operation for Superconducting Quantum Interference Filters
A. V. Shadrin, K. Y. Constantinian, G. A. Ovsyannikov +4
A new operating regime of the Superconducting Quantum Interference Filter (SQIF) is investigated. The voltage to magnetic field response function, V(H), is determined by a Fraunhof…
Spontaneous Fluxon Production in Annular Josephson Tunnel Junctions in the Presence of a Magnetic Field
R. Monaco, M. Aaroe, J. Mygind +2
We report on the spontaneous production of fluxons in the presence of a symmetry-breaking magnetic field for annular Josephson tunnel junctions during a thermal quench. The depende…
