This review focuses on the superconducting properties of MgB 2 that are relevant for power
applications. The reversible mixed state parameters are the most important, since they …

A review of our investigations on single crystals of LnFeAsO1− xFx (Ln= La, Pr, Nd, Sm, Gd)
and Ba1− xRbxFe2As2 is presented. A high-pressure technique has been applied for the …

A much-needed update on complex high-temperature superconductors, focusing on
materials aspects; this timely book coincides with a recent major break-through of the …

LiTi2O4 is a unique compound in that it is the only known spinel oxide superconductor. The
lack of high quality single crystals has thus far prevented systematic investigations of its …

We demonstrate that images of flux vortices in a superconductor taken with a transmission
electron microscope can be used to measure the penetration depth and coherence length in …

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 …

Point-contact measurements on the carbon-substituted Mg (B 1− x C x) 2 filament/powder
samples directly reveal a retention of the two superconducting energy gaps in the whole …

Raman scattering spectra from the ac face of thick M g B 2 single crystals were measured in
zz, xz, and xx polarizations. In zz and xz polarizations a threshold at around 29 cm-1 forms in …

We use the functional integral approach to study low energy collective excitations in a
continuum model of neutral two-band superfluids at T= 0 for all couplings with a separable …

The discovery by JG Bednorz and KA Müller in 1986 that the superconducting state can exist
in oxides at temperatures above 30 K stimulated research in the field of superconductivity …
