We have established a plot of the anion height dependence of superconducting transition
temperature T c for the typical Fe-based superconductors. The plot showed a symmetric
curve with a peak around 1.38 Å. Both data at ambient pressure and under high pressure …

This paper describes the present status of high temperature superconductors (HTS) and of
bulk superconducting magnet devices, their use in bearings, in flywheel energy storage
systems (FESS) and linear transport magnetic levitation (Maglev) systems. We report and …

This topical review summarizes various features of magnetic penetration depth in
unconventional superconductors. Precise measurements of the penetration depth as a
function of temperature, magnetic field and crystal orientation can provide detailed …

The application of superconducting fault current limiters (SCFCLs) in power systems is very
attractive because SCFCLs offer superior technical performance in comparison to
conventional devices to limit fault currents. Negligible impedance at normal conditions, fast …

Less than two years after the discovery of high temperature superconductivity in oxypnictide
LaFeAs (O, F) several families of superconductors based on Fe layers (1111, 122, 11, 111)
are available. They share several characteristics with cuprate superconductors that …

Superconducting magnets have a variety of industrial, medical and research applications.
This review discusses the prospects for MgB 2 superconductor for practical magnet
applications vis-à-vis the intermetallic low (LTS) and high temperature superconductor  …

A variety of synthetic strategies has been employed to prepare pure monophasic cuprates of
different families with good superconducting properties. Besides the traditional ceramic
method, other methods such as coprecipitation and precursor methods, the sol-gel method …

This paper presents a topical review of the current state of the art in modelling the
magnetization of bulk superconductors, including both (RE) BCO (where RE= rare earth or
Y) and MgB 2 materials. Such modelling is a powerful tool to understand the physical …

This paper presents a new numerical model for computing the current density, field
distributions and AC losses in superconductors. The model, based on the direct magnetic
field H formulation without the use of vector and scalar potentials (which are used in …

The discovery of superconductivity at relatively higher temperatures in a non-cuprate
system, LnFeAsO 1− x F x (Ln= lanthanides) has created tremendous activity among the
reseachers in this field. This review is an overview on the present status and the future …
