The primary goal of this work was to identify one-phase regions of the phase diagrams for methanol/H2O/CO2 mixtures and acetonitrile/H2O/CO2 mixtures over the temperature range of 25°–100°C. These mixtures are expected to be useful for efficient

L10 FePt nanoparticle assemblies consisting of a few layers of 4-nm-diameter particles, are a potential data storage medium beyond 1 Tbit/in2. However, annealing at temperatures >500 °C is required to form the high anisotropy L10 phase. Recent studi

The response of the superconducting charge carriers to an applied magnetic field has been probed in a number of organic superconductors using μSR. Systematic studies have been made of the in-plane superconducting penetration depth λ in superconduct

In the mixed state of ${\mathrm{Bi}}_{2.15}{\mathrm{Sr}}_{1.85}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}$ the temperature dependence of the muon spin rotation ( $\ensuremath{\mu}\mathrm{SR}$) linewidth is found to have a strong field de

The μ2‐scaled Huckel method is used to calculate the electronic energy surfaces of the four boranes BnH2−n (n=8–11) and the carborane C2B8H2−10. These electronic energy surfaces and their minimum energy geometries are directly compared to bo

A flux‐line lattice (FLL) was observed in a single crystal of Bi2.15Sr1.95CaCu2O8+x (BSCCO) using small‐angle neutron scattering methods. The sample has a superconducting transition at 85 K. The flux‐line lattice is observed to melt, evidenced

We report on small angle neutron scattering observations of the flux line lattice (FLL) in a single crystal of YBa[sub 2]Cu[sub 3]O[sub 7]. To probe the mass anisotropy ratio, [ital m][sub 3]/[ital m][sub 1], measurements were made as a function of a

Neutron diffraction has been used to measure the vortex lattice scattering for YBa2Cu3O7. A square pattern is found when the field is applied along the c axis, while a triangular pattern is found when the field is applied well away from the c axis. H

The in-plane magnetic penetration depth ${\ensuremath{\lambda}}_{ab}$ in optimally doped $(\mathrm{BiPb}{)}_{2}(\mathrm{SrLa}{)}_{2}{\mathrm{CuO}}_{6+\ensuremath{\delta}}$ (OP Bi2201) was studied by means of muon-spin rotation. The measurements of ${
