            Pseudo-Gap Properties in HTSC                            


                      PG structures observed in optical conductivity in the range of 50–150 cm−1

                      are uniquely driven by the SC correlation,  and the magnetic correlation

                      coexists in the far separated range of about 700 cm−1
