First, this paper gives an overview of possible origins and mechanisms that might be responsible for experimentally observed nonlinear effects. Focusing on well-known physical loss mechanisms with nonlinear characteristics, their impact on microwave

The preparation of the switching element of a resistive superconducting fault current limiter requires the up-scaling of deposition techniques for thin YBa 2 Cu 3 O 7−δ (YBCO) films to large areas and high film thicknesses. For a projected 100 kVA

Due to the extreme demands of high-temperature superconductor (high-T c HTS) materials – especially the extremely complex structure, small coherence length and large anisotropy – existing deposition technologies have been greatly improved and nov

A model for vortex depinning and motion is presented, which takes into account the inhomogeneity of a real type-II superconducting sample. The model is based upon a mechanism in which the flux-line lattice is depinned by synchronous shear around vort

It is demonstrated that the low-frequency noise due to vortex motion in high-temperature superconducting quantum interference devices (SQUIDs) in ambient magnetic fields can strongly be reduced by a simple arrangement of antidots patterned into the S

The physical properties of RBa 2 (Cu 1- x T x ) 3 O 7- δ , R=Y/Gd, T=Ni/Fe are represented. Bulk samples of different concentrations of the magnetic ions up to 100% are prepared and the oxygen contents, structure, microstructure, magnetic and critic

Magnetization measurements of the intragranular pinning force in polycrystalline YBa2Cu3O7−δ and YBa2(Cu1−xMx)3O7−δ, where M = Fe,Ni, address two major questions of flux pinning: 1, what are the dominant pinning sites; and 2, what is the rele

Scanning Hall probe microscopy has been used to make a microscopic study of flux structures and dynamics in yttrium barium copper oxide thin-film disks containing a regular $10\text{\ensuremath{-}}\ensuremath{\mu}\mathrm{m}$-period square array of $2
Controlled trapping and guided motion of vortices via special arrangements of micro-holes, so-called antidots, in YBa2Cu3O7 films and devices is demonstrated. Resistive Hall-type measurements prove the presence of guided flux motion along rows of ant
