We review experimental studies of the time decay of the nonequilibrium magnetization in
high-temperature superconductors, a phenomenon known as magnetic relaxation. This …

The critical-state behavior of an infinitely long type-II superconducting thin-film strip is
theoretically analyzed for an arbitrary sequence of applied transport currents and …

We have studied an anomalous peak effect in a Bi 2 Sr 2 CaCu 2 O 8+ y single crystal using
a specially designed Hall probe magnetometer. In order to investigate the origin of the …

The layered structure of superconducting cuprates is the origin of the anisotropic
conductivity in the normal state and the anisotropic energy gap and anisotropic critical …

A review of recent results on nonlinear diffusion of magnetic flux in high-Tc superconductors
is given. Making use of a universality of thermally-activated flux diffusion, one can formulate …

The interlayer phase coherence in Bi 2 Sr 2 CaCu 2 O 8+ y was quantitatively determined in
a wide field range by using the Josephson plasma resonance (JPR). At the first-order …

An exact solution of the nonlinear integral equation is obtained that describes flux creep in
strips or disks. We calculate both analytically and numerically the relaxation of the electric …

We report direct imaging of the critical state in a YBa 2 Cu 3 O 7− y single crystal. The self-
field profiles are obtained by mechanically scanning a high-spatial-resolution Hall-probe …

The critical current (I,) of YBa2Cu307.-s grain boundary Josephson junctions was measured
up to magnetic fields of 5 T. Magnetic field history dependent 1, values were observed even …

We report superconducting properties of single crystalline Ca 10 (Pt 4-δ As 8)(Fe 2-x Pt x As
2) 5 by x-ray diffraction, magnetization, resistivity, and magneto-optical imaging …
