Calculate the lattice constant, a, of the cubic unit cell. If the space lattice is SC, the lattice constant is given by the formula a = [2 x r]. For example, the lattice constant of the SC-crystallized polonium is [2 x 0.167 nm], or 0.334 nm. If the space lattice is FCC, the...
Copper, for instance, has a FCC structure. Such cells are called cells with basis (or Bravais lattices). Crystallographic directions are characterized by identity distances (periods), i.e., the shortest distance between identical atoms in a given direction. Parallel crystallographic planes are also...
Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous nanofoam structure. We find
Given the constant lattice distances along the 〈111〉 direction in SD, this results in a shortening of the distances between A, D and next atom along the Z-axis direction of B atom. Although no obvious hard core reconstruction is observed, this can be interpreted as a trend from the ...
Furthermore, the stretched exponential characteristics indicate that hopping of the QPs is a continuous- time random walk with a time dependent diffusion constant28–31: ∂ ∂t N (t, z) = ∂ ∂z Dt−γ ∂ ∂z N (t, z), (1) where N...

Depar-ture from cubic symmetry in Tb was reported to set inbelow 20 K becoming constant below 10 K (Bleaney, Ste-phen, Walker, Wells, 1982). A slightly smaller ionic radiusamong lanthanides having higher atomic numbers, a prop-erty that Y shares with this part of the rare earth series(...
The lattice constant a of the pristine diamond was predicted to be 3.563 Å, showing good agreement with the experimental value of 3.567 Å. In particular, a supercell was built up from the equilibrium diamond cell with lattice vectors defined as [110], [\(\bar{1}10\)], and [...
The transition rates for all events in the system are calculated according to the Arrhenius formula for thermally activated processes:(1)Γ=νexp-EmkBT,where ν is the attempt frequency for the transition to occur, kB is the Boltzmann constant, T is the temperature of the system, Em is the...
