Superconducting magnets have a variety of industrial, medical and research applications.
This review discusses the prospects for MgB 2 superconductor for practical magnet …

Magnetization and its relaxation have been measured in Ba (Fe 1− x Co x) 2 As 2 single
crystals at various doping levels ranging from very underdoped to very overdoped regimes …

By measuring the dynamic and traditional magnetization relaxations we investigate the
vortex dynamics of the recently discovered superconductor SmFeAsO 0.9 F 0.1 with T c= 55 …

Abstract A high-quality FeSe 0.5 Te 0.5 single crystal with T c∼ 14.8 K was obtained by the
self-flux method. We present the temperature dependence of resistivity at various fields and …

We have investigated the pinning of vortices in high-J c films of polycrystalline MgB 2, by
studying the dependence of current density J on electric field E using both magnetic and …

Thermally-activated flux flow (TAFF) resistivity above the irreversibility field B i is reported for
two different c-axis textured MgB 2 superconducting films. Transport measurements at …

High-quality bulk MgB2 exhibits a structure of voids and agglomeration of crystals on
different length scales. Because of this, the superconducting currents percolate between the …

We have conducted extensive investigations on the magnetization and its dynamical
relaxation on a Ba 0.66 K 0.32 BiO 3+ δ single crystal. It is found that the magnetization …

The current-voltage (IV) characteristics of various Mg B 2 films have been studied at different
magnetic fields parallel to the c axis. At fields μ 0 H between 0 and 5 T, vortex liquid-glass …

Critical current density, transport properties, and magnetic relaxation have been investigated
in (Li 1− x Fe x) OHFeSe single crystals at different temperatures and magnetic fields. A …
