Incommensurate multisoliton regimes in the bismuth—type high T_csuperconductors

Abstract

A systematic investigation by transmission electron microscopy on bismuth oxide superconductors, has established existence of discommensurations. This investigation on the (22011, (2212) and (2223) phases of this material shows that discommensurations exist with various "latenttt lock-in wavevectors between -b* and E.
