Abstract
Superconductivity of gallium embedded in the porous glass with average pore size of 4 nm was studied for the first time using a SQUID magnet ometer. A sharp superconducting phase transition was found at 6.4 K. H ysteretic behavior at high and low magnetic fields was observed. The p hase diagram in the H-T plane was obtained. The first order phase tran sition in the vortex system was observed. A qualitative model of the s uperconducting properties of the porous glass with gallium has been de veloped.
