In oxygen-annealed La 2 CuO 4+δ (δ ∼0.03), bulk magnetization measurements show an increase of ∼4K in the superconducting T c when the sample is cooled slowly through a narrow temperature range near 195K. At this temperature, 139 La NQR spectra

A two-phase refinement of a crystal for the compound La2CuO4+δ (δ=0.032), based on the neutron diffraction data collected at 15 K with the D9 diffractometer at ILL, using ǂ=0.48 A , has been carried out. One phase (30%) consists of stoichiometric

NMR and NQR reveal substantial structural changes in the metallic phase of La2CuO4+δ which occur below 220 K. The oxygen octahedra in the metallic phase are not tilted at phase separation; upon cooling to 40 K considerable tilt has developed. The lo

Pressures above 8 kbar have been shown to quench the low-temperature phase changes in U permitting retention of the ..cap alpha..-U phase to liquid-He temperatures. Field-modulation de Haas--van Alphen measurements are then possible at pressures >8 k

The crystal structure of superconducting (37.5 K) La2CuO4.032 has been refined from single-crystal neutron-diffraction data at room temperature and 15 K. At both temperatures it exhibits the orthorhombic symmetry Cmca. The extra oxygen O4 atoms occup
