概要
- 論文の詳細を見る
A crystal structure of Tl_2Ba_2CuO_<6+x> oxide, which was not a superconductor, was studied by an electron microscope. The unit cell parameters are a=b=3.85 Å and c=23.02 Å. The crystal was found to be one of a series of compounds expressed by Tl_2Ba_2Ca_nCu_<n+1>0_<2(3+n)+n> in Tl-Ba-Ca-Cu-O (TBCCO) oxide systems. The crystal has an incommensurate superstructure modulation in the (100) planes, whose occurrence is different from the (110) plane modulation found in Bi-Sr-Ca-Cu-O (BSCCO) systems. The modulation takes place in the BaO-TlO-TlO-BaO slabs with a period 6.6×a along the [100] direction.
