| Popis: | Nuclear quadrupole resonance (NQR) of 63 65 Cu is observed in the 2223-phase of Tl 2 Ba 2 Ca 2 Cu 2 O 10 ( T c =121 K) and (Bi 1.6 Pb 0.4 )Sr 2 Ca 2 Cu 3 O 10 ( T c =110 K). The electric quadrupole interactions at two Cu sites (in the Cu-O pyramid and in the Cu-O square plane) are distinguished and are compared with those in other T c superconductors. |
