The 90 K superconductor, YBa2Cu3Oδ (YBCO), has proved to be highly adaptable
chemically as it can accommodate a wide variety of cationic and anionic substitutions …

Optical conductivity spectra of conducting oxides, cuprates, including high-Tc
superconductors, nickelates, manganites, doped titanates, barium–lead–bismuth oxides …

The structural, magnetic, and superconducting properties of the mixed compounds La 1.85
Sr 0.15 Cu 1− x M x O 4 (0< x< 0.3)(M= Ni or Zn) and Y Ba 2 Cu 3− x Ni x O 7− y (x= 0.25 or …

High-Temperature Superconductors provides an up-to-date and comprehensive review of
the properties of these fascinating materials. Much has been learned about the behavior and …

We have investigated the effect of aluminum incorporation on the structure and
superconducting transition temperature of single crystals of high-T c cuprate perovskite …

We present the results of a neutron powder-diffraction study on YBa 2 Cu 3− x Co x O 7− y.
We find that Co preferentially occupies the Cu (1) site, simultaneously attracting extra …

Abstract The Bi 4 Sr 4 Ca 2− x R x Cu 4 BO y materials (R is a rare-earth element) were
studied to determine their structural and physical properties. For most of the rare-earth …

Abstract Superconducting Y 1 Ba 2 Cu 3 O 7− x films were produced by metal molecular-
beam epitaxy with one electron beam and two thermal cells and a molecular oxygen-gas …

Publisher Summary This chapter discusses the structural studies performed on
superconducting oxides. It focuses primarily on Y 1 Ba 2 Cu 3 O 7–δ, nicknamed the 123 …

Dopant site occupancies in YBa 2 Cu 3− x M x O 7− δ, with M= Fe (x= 0.3 and x= 0.5), Co (x=
0.2 and x= 0.5), Ni (x= 0.3), and Zn (x= 0.3) have been found using differential anomalous x …
