Abstract
The influence of pressure (up to 1 GPa) on the superconducting properties of ReBal.sSro.sCu306+= (Re=Y,Gd) ceramics has been studied in the interval of T = 4-100 K. The pressure effect depends strongly on the oxygen contents. The dTc/dP = 20K/GPa (for Re = Yi x = 0.56) is the highest value for HTSC of 123 type. Under a prolonged action of pressure at room temperature the relaxation of Tc as well as hysteretic phenomena with pressure have been observed. The relaxation times of Tc under pressure are determined. These effects are interpreted as being due to the oxygen ordering in CuO chains.
