Single-crystal, stage-1 IBi2Sr2CaCu2Os+ x was synthes~zext. X-ray diffraction patterns indicate that upon intercalation, the c-axis correlation length decrea.,,,s substantially, but the in-plane host layer structure appears to remain unchanged. The compounds exhibit resonance Raman scattering. Raman

Polycrystalline material of approximate composition Te2Ba 2 Ca Cu2Os was synthesized by melting oxides together, pressing pellets and heating in sealed quartz tubes. High resolution synchrotron X-ray powder data obtained at beam-lineoXTA at the National Synchrotron Light Source revealed a tetragonal
The dynamic magnetic hysteresis loops m(T, B a , B Λa) of an epitaxial Tl 2 Ba 2 CaCu 2 O 8 superconducting thin film are measured at various field sweep rates B Λa and at temperatures ranging from (1/2)T c to (4/5)T c . The magnetization current densities J m (T, B a , B Λa) are obtained using the
