Single-crystal study of the 55 K superconductor TlSr{sub 2}CaCu{sub 2}O{sub 7}{sigma}
- Universite de Caen (France); and others
Single crystals of the TlSr{sub 2}CaCu{sub 2}O{sub 7} superconductor have been grown for the first time. The structures of an as-grown crystal (T{sub c} = 55 K) and an oxygen pressure annealed one (T{sub c} = 15 K) have been refined. The results are compared to those reported for the polycrystalline phase. The magnetic study (H{vert_bar}{vert_bar}c) of a T{sub c} = 55 K as-grown crystal allows the comparison of the superconducting properties of TlSr{sub 2}CaCu{sub 2}O{sub 7} with those of other thallium 1212 single crystals. 22 refs., 7 figs., 3 tabs.
