The infrared region of the spectrum has been of great interest to researchers for many years
with the mid-to far-IR frequency region from about 100 to 3800 cm 1 of particular interest …

The low magnetic field vortex patterns nucleation and evolution in a high-quality two-gap
superconductor MgB 2 single crystal have been investigated by low-temperature scanning …

Bitter decoration and magneto-optical studies reveal that in heavy-ion irradiated
superconductors, a “porous” vortex matter is formed when vortices outnumber columnar …

Using a differential magneto-optical technique to visualize the flow of transport currents, we
reveal a new delocalization line within the reversible vortex liquid region in the presence of …

We present a comprehensive overview of vortex pinning in single crystals of the isovalently
substituted iron-based superconductor BaFe 2 (As 1− x P x) 2, a material that qualifies as an …

We consider the melting of the vortex solid in highly anisotropic layered superconductors
with a small concentration of random columnar pinning centers. Using large-scale numerical …

Theoretically, the vortex melting phenomenon occurs at both low and high magnetic fields at
a fixed temperature. While the high-field melting has been extensively investigated in high-T …

We have studied nonequilibrium phase transitions in the vortex lattice in superconducting
MgB 2, where metastable states are observed in connection with an intrinsically continuous …

The past four years (1997–2001) have seen many exciting developments in high
temperature superconductivity, most notably the discovery of the superconducting nature of …

We study the melting transition of the low-temperature vortex solid in strongly anisotropic
layered superconductors with a concentration of random columnar pinning centers small …
