Abstract
The behaviour of crystallographic, acoustic parameters and magnetic su sceptibility for HTSC polycrystalline compounds (123, 124 in Y-BA-Cu-O system and 2201, 2212, 2223 in Bi-Srr-Ca-Cu-O system degrees in tempe rature range 80 - 300 K near known anomalies at T-1 = 210 - 270 K and T-2 = T-c + 15 K has been investigated. We have suggested thy hypothes is of antiferromagnetic type interactions in Cu-O structural fragments rising at T-1 and superconducting transition due to these interaction s at T-2.
