Abstract

The platelet bulk specimen Bi₂Sr₂CaCu ₂O_y sandwiched between Ag disks was shocked to 5 GPa using shock loading method. The shocked specimen showed high orientation to c-axis and consolidation of high density of 95 %. Ag particles of about 10 nm were observed on the surface of Bi₂Sr₂CaCu₂O _y specimen by TEM. The magnetization of zero field cooling strongly increased and T_c reached to 8 4 K from 74 K by the annealing at 650°C for 12 hs in N₂ after shock loading. The ΔM (the difference of FC and ZFC) was enhanced about 50 times than pristine specimen. The introduction of pinning site was discussed in connection with jetting effects of shock wave.
