We report here a simple and efficient synthetic route to high-temperature superconducting oxyfluorides. Solid phase fluorination of Sr 2 CuO 3 with NH 4 F at relatively low temperatures produces superconducting Sr 2 CuO 2 F 2+δ ; this simple prepara

The synthesis of the copper oxyfluoride, Ca2CuO 2F2+δ1, by reaction of Ca2CuO3 with elemental F2 at low temperatures (240°C) is reported. Preliminary structure refinement of powder neutron diffraction data suggests that Ca2CuO2F2+δ is structurally

High quality, c-axis oriented thin films of semiconducting La{sub 2}CuO{sub 4} have been fabricated by pulsed laser-ablation deposition. Superconducting properties have been successfully induced in the films by a postdeposition, ex-situ static anneal

Pulsed laser ablation has been used to fabricate La2CuO4 thin films. Superconducting properties have been successfully induced in the films by an ex-situ, post-ablation annealing process in F2 gas resulting in a Tc (onset) of 36 K. The presence of tw

Ultrafine magnetic cobalt particles, encapsulated within a zeolitic host, have been prepared via the seldom-used method of salt occlusion followed by reduction to the metallic state. Powder X-ray diffraction and electron microscopy clearly showed the

A solid solution of the quasi-one-dimensional cuprate, (Ca1-xYx)0.82CuO2 with 0 ≤ x ≤ 0.435, has been successfully synthesized at room pressure. Upon yttrium doping (decreasing hole concentration), the formal Cu valence of the solid solution chan

X-ray and neutron diffraction as well as magnetometric measurements performed for HoPtX and ErPtX (X = Si, Ge) compounds indicate that they are crystalline and that they have the orthorhombic TiNiSi-type crystal structure. They are antiferromagnetic

We have investigated the properties of a series of YBCO thin films of 230 nm thickness deposited onto SrTiO3 substrates (001) with a vicinal off-cut angle between 0° and 6° in steps of 1°. RBS angular scans demonstrate the high degree of alignment

The magnetic properties of polycrystalline samples of PrCuSn and NdCuSn, including their magnetic structures, were determined by magnetic and neutron diffraction measurements. Both compounds show the hexagonal, -type crystal structure and are antifer
