The nonlinear surface impedance and intermodulation distortion (IMD) products of MgB2 thin films have been measured as a function of temperature. The measurements use a stripline-resonator technique, following an approach that was developed and exten

Recently, evidence has been presented by this group that the measured intermodulation distortion (IMD) in YBa2Cu3O7-x (YBCO) films of high quality is consistent with the intrinsic limit, given by the d-wave order parameter. This intrinsic nonlinearit

Intermodulation distortion (IMD) in high-T/sub c/ superconductor (HTS) devices continues to be important, and a complete understanding is lacking. We have measured the third-order IMD vs power as a function of temperature from 1.7 K to T/sub c/ for Y

Measurements of the intermodulation distortion (IMD) as a function of temperature from 1.7 K to Tc in Y Ba2Cu3O7−δ are presented. Films of the highest quality show an increase in IMD as the temperature decreases for temperatures below approximatel

The nonlinear reactive response of a thin superconductor strip at microwave frequencies is analyzed in terms of two mechanisms intrinsic to a superconductor: the response of the condensate state in the presence of an electromagnetic transversal field

A widely used configuration in superconductivity-based electronics is a thin superconductor strip in the presence of a normally incident magnetic field. For a weak magnetic field, close to the vortex-penetration threshold field, the vortex-penetratio

Exact expressions for a normally aligned vortex-structure in an isotropic superconductor film and strip are derived. The ensuing thickness-dependent vortex localization at the surface is analyzed.

The geometrical barrier of a high aspect-ratio non-thin superconductor strip in the presence of a weak, normally-incident applied magnetic field is calculated employing exact expressions for the response of and vortex-structure in a strip. The calcul

The response of an infinitely long superconductor strip in its virgin state to a normally incident magnetic field is calculated. The non-divergent, analytic expressions for the screening current and magnetic field apply for a strip of arbitrary width

It is shown that there are two vortex states for the configuration of an Abrikosov vortex in the presence of a long Josephson junction. One state, dubbed `conventional', carries one magnetic-flux quantum Φ 0 , as does the generating Abrikosov vortex
