Examples include the detection of weak oxygen ordering, description and characterization of deformation modulations in layered superconductors, and analysis of very long period superstructures. The ordering principles for tetrahedral chains in Ga\u2010, Co\u2010, or Al\u2010substituted YBCO are discussed and their complex defect structures are described. The incommensurate modulation in YBCO\u2010based materials containing SO<jats:sub>4<\/jats:sub>\u2010tetrahedra, centered on the Cu(1) sites of the CuO\u2010chain plane is attributed to the ordering of b\u2010oriented SO<jats:sub>4<\/jats:sub>\u2010rich chains in the Cu(1)\u2010S\u2010O layer; the structure is described in terms of an SO<jats:sub>4<\/jats:sub>\u2010concentration wave. As examples of the new mercury\u2010based superconducting family we discuss Y<jats:sub>0.6<\/jats:sub>Ca<jats:sub>0.4<\/jats:sub>Ba<jats:sub>2<\/jats:sub>Hg<jats:sub>1\u2212x<\/jats:sub>M<jats:sub>x<\/jats:sub>Cu<jats:sub>2<\/jats:sub>O<jats:sub>6+y<\/jats:sub>, which crystallizes in the space group P4\/mmm with a = 0.3870(1) nm, c = 1.2537(1) nm. This cuprate belongs to the 1212 series; susceptibility measurements show a T<jats:sub>c<\/jats:sub> (onset) of 90K, with a diamagnetic volume fraction of 27% at 4.2K to be reached. A second example is related to the compound Tl<jats:sub>2<\/jats:sub>HgBa<jats:sub>4<\/jats:sub>Cu<jats:sub>2<\/jats:sub>O<jats:sub>10+y<\/jats:sub>, in which ordering between single Hg layers and double Tl layers is observed. \u00a9 1995 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/jemt.1070300203","type":"journal-article","created":{"date-parts":[[2005,2,23]],"date-time":"2005-02-23T16:58:05Z","timestamp":1109177885000},"page":"102-122","source":"Crossref","is-referenced-by-count":3,"title":["Structural investigations of recently discovered high T<sub>c<\/sub> superconductors"],"prefix":"10.1002","volume":"30","author":[{"given":"G.","family":"Van Tendeloo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Krekels","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Amelinckx","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.
