The Electronic Structure of Hexagonal BaCoO3
Journal of Solid State Chemistry, 1999Abstract TB–LMTO–ASA band structure calculations within the local spin density approximation have been performed to explain the magnetic and transport properties of BaCoO3. The calculations predict a magnetic and metallic ground state as energetically favored. BaCoO3 shows no long-range magnetic ordering, however, and only poor conductivity.

Optics Letters, 2012
We present the hexagonal digital moiré method for three-directional structural characterization of hexagonal packed nanostructures. A mismatch between a three-way grating and a nanoparticle assembly is shown to produce hexagonal moiré fringes due to the interference between three groups of parallel moiré patterns.

Structure of Hexagonal Silver Iodide
The Journal of Chemical Physics, 1963A detailed three-dimensional refinement of the structure of hexagonal silver iodide from room-temperature photographic data showed very little deviation from the ideal wurtzite-type structure. Using anisotropic temperature factors a final R value of 6.6% was obtained. The space group is P63mc, a=4.592, c=7.510, c/a=1.635, μ=0.3747.

Structural properties of hexagonal boron nitride
Modelling and Simulation in Materials Science and Engineering, 2006The electronic and structural properties of hexagonal boron nitride (BN) were studied using density functional theory calculations. Three different approximations for the exchange—correlation energy (the local density and two forms of the generalized gradient)—were used to calculate properties such as the bulk modulus, cohesive energy and lattice ...

The magnetic structure of hexagonal ErAl3
Physics Letters A, 1971Abstract Hexagonal ErAl3 has been studied by neutron diffraction and the magnetic structure has been determined. ErAl3 orders antiferromagnetically with the moments directed along the c-axis. The observed magnetic moment is 6.15 μB at 2.15° K.

Hexagonal vs Triangular Core Lightweight Mirror Structures
Applied Optics, 1972The higher rigidity of a lightweight mirror structure with core ribs that form hexagonal cells, as compared with triangular cells, is demonstrated by holographic deflection measurements on 75-cm diam acrylic structural models.

Formation of ordered hexagonal fiber structures
Journal of Optical Technology, 2003Based on a solution of the problem of creating structures similar to point and line television rasters, a method has been developed for forming an ordered hexagonal fiber structure, based on the simplest transformations of the classical shape of assembly elements.

Electronic structure of hexagonal iron layers
Journal of Magnetism and Magnetic Materials, 1991Abstract Using a tight-binding Hamiltonian, the recursion method and a self-consistent Stoner criterion to calculate the magnetic moments we have investigated the magnetism of 6 hexagonal layers of Fe between ruthenium layers on each sides. With ferromagnetic spin-polarization we obtain a magnetic moment of about 2μ B per atom in the 4 inner iron ...
