Analytical microscopy of iron-based superconducting materials
Inhomogeneity and phase separation in unconventional superconducting materials is a topic of increasing interest, as the competition between phases with different types of ordering is thought to play an important role in the emergence of the high temperature superconducting state. A wide range of experimental techniques are available for investigating the crystallography of these complex materi...
متن کاملLight-superconducting interference devices
Recently, we have proposed the half-Josephson laser (HJL): a device that combines lasing with superconducting leads, providing a locking between the optical phase and the superconducting phase difference between the leads. In this work, we propose and investigate two setups derived from a superconducting quantum interference device (SQUID), where two conventional Josephson junctions are replace...
متن کاملMagnetic properties of the superconducting state of iron-based superconductors
We show that features of the dynamical spin susceptibility can unambiguously distinguish between different pairing symmetries of the superconducting state in iron-based superconductors. A magnetic resonance is a feature for the extended sx2y2-wave cos kx cos ky pairing symmetry. It is present in the pure superconducting SC state but weakens in the mixed SC and magnetically ordered state. We cal...
متن کاملSuperconducting quantum interference devices based on YBaCuO nanobridges
Direct current SQUIDs based on YBaCuO thin film nanobridges have been investigated. Critical current densities Jc of the devices are up to 3310 6 A/cm at T577 K and show a temperature dependence of (12T/Tc) . High values of the voltage-flux modulation are observed ~8 mV peak to peak at 77 K, 45 mV at 4.2 K!. The temperature dependence of the SQUID modulation is found to be essentially different...
متن کاملSuperconducting memories employing Josephson devices
Experimental super conducting Josephson devices being investigated for use in digital logic and memory circuits have been demonstrated to switch in the 10 to 100 picosecond (1 picosecond = 10-12 sec) range. Projections based on the operation of individual logic circuits indicate that they may surpass semiconductor circuits in very high performance CPU's. This potential is based on the fact that...
