Total energy local density determinations of the effects of pressure on the (Srt\_xCax h\_yCuO2 infinite layer (IL) Tc ffi 110 K superconductor show, that the compressibility is highly anisotropic. Surprisingly , the energy location of the van Hove singularity (vHs) moves towards EF with pressure, t

The infinite-layer phase existing in the compounds with composition Sr~\_xRexCuO2 (Re=Pr, La) synthesized under high pressure has been investigated by high-resolution transmission electron microscopy as well as selected-area electron diffraction techniques. A few stacking faults with a/2 shear vecto
Electrical resistivity and diamagnetic susceptibility have been measured for high-quality single crystals of NbTe 2. The su~rconducting transition is observed at T c of 0.5 K. The transition to the superconducting state depends strongly on the current density. Susceptibility Xl[ = M/H with applied m
