Single crystal neutron scattering measurements have been performed on the spin-ladder compound Sr 14 Cu 24 O 41 at 7 K. The incommensurate composite structure has been determined using the superspace group formalism. The low-temperature structure doe

Inelastic coherent neutron scattering experiments have been performed to study the low-frequency structural excitations in single crystals of the incommensurate superconducting Bi2Sr2CuO6 + δ (Bi-2201) system. As in the Bi-2212 family, the observati

We present neutron scattering investigations of the structural dynamical properties of the aperiodic layered compound, Bi2Sr2CaCu2O8 + δ. Acoustic phonons behave identically around the assumed average structure Bragg reflection and around the first

The inverse of the NQR or NMR spin lattice relaxation time of BCPS exhibits a Landau like critical behaviour on approaching the Normal/Incommensurate phase transition from above. This critical behaviour is interpreted as the contribution from the cen

We have performed elastic neutron scattering experiments, using a high-quality single crystal of the high-${T}_{c}$ superconductor ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}.$ By a systematic comparison

We report the first very low-temperature specific-heat data of the incommensurate n-nonadecane/urea inclusion compound. In addition to the contribution due to normal acoustic phonons, the results show a linear temperature dependence of the specific h

Etching of InGaAs and InP in inductively coupled plasma (ICP) using SiCl4 was studied for heterojunction bipolar transistor (HBT) applications. Low sample temperature was used to minimize etching isotropy and to reduce group V element desorption. The

Nuclear magnetic resonance (NMR) experiments, 35Cl nuclear quadrupole resonance (NQR) and 2H NMR, have been performed close to the displacive normal-incommensurate phase transition in the organic crystal of bis-(4-chlorophenyl)-sulfone. Calculations

We report the results of an inelastic neutron scattering study of the lattice vibration spectra in the normal and incommensurate phases of $({\mathrm{ClC}}_{6}{\mathrm{D}}_{4}{)}_{2}{\mathrm{SO}}_{2}$. Because of unusually low soft mode damping, a fi
