Resonant Spin Excitation in an Overdoped High Temperature Superconductor

, 2001
An inelastic neutron scattering study of overdoped Bi_2Sr_2CaCu_2O_{8+\delta} $ (T_c = 83 K) has revealed a resonant spin excitation in the superconducting state.

Vortex Nanoliquid in High-Temperature Superconductors [PDF]

Physical Review Letters, 2004
Using a differential magneto-optical technique to visualize flow of transport currents, we reveal a new delocalization line within the reversible vortex liquid region in the presence of a low density of columnar defects. This line separates a homogeneous vortex liquid, in which all the vortices are delocalized, from a heterogeneous "nanoliquid" phase ...

Superfluid Inhomogeneity and Microwave Absorption in Model High-T_c Superconductors

, 2002
We investigate the microwave absorption arising from inhomogeneity in the superfluid density of a model high-T_c superconductor. Such inhomogeneities may arise from a wide variety of sources, including quenched random disorder and static charge density ...

Collective modes in high-temperature superconductors [PDF]

Physical Review B, 1998
The role of collective modes in various experiments on the cuprates is investigated. We calculate the neutron scattering, photoemission (ARPES), and Raman scattering intensities below $T_c$ within the fluctuation-exchange (FLEX) approximation for the two-dimensional Hubbard model.

Thermal effects associated with the crack of high-temperature superconducting magnetic levitation system

AIP Advances
Based on the magnetic flux pinning characteristics of the non-ideal type II superconductor YBa2Cu3O7−x, the high-temperature superconducting magnetic levitation system has the advantages of self-stability in levitation and low energy consumption. Thermal

Anomalous density of states in a metallic film in proximity with a superconductor

, 2003
We investigated the local electronic density of states in superconductor-normal metal (Nb-Au) bilayers using a very low temperature (60 mK) STM. High resolution tunneling spectra measured on the normal metal (Au) surface show a clear proximity effect ...

Analysis of the Processes of Short-Currents Limiting by Transformer with High-Temperature Superconducting Windings [PDF]

Problems of the Regional Energetics, 2017
An important advantage of transformers with high-temperature superconducting winding is their ability to limit the short-circuit currents. The article discusses a physico-mathematical model that analyses transient processes at short-circuit currents in ...
