Magnesium diboride (MgB 2) single crystals, with a maximum size of 0.5× 0.5× 0.02 mm 3,
were grown by the vapor transport method in a sealed molybdenum crucible. A …

Here we report the growth of sub-millimeter MgB 2 single crystals of various shapes under
high pressure in Mg–B–N system. Structure refinement using a single-crystal X-ray …

The influence of anisotropy on the transport current in M g B 2 polycrystalline bulk samples
and wires is discussed. A model for the critical current density is proposed, which is based …

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 …

We report on the study of the electronic anisotropy of the MgB 2 superconductor using the in-
plane resistivity measurements in the magnetic field applied perpendicular and parallel to …

The basic physical properties of MgB2 have been well established over the past two years of
intensive research. At this point there is a general consensus about the values for the …
