Crucially, a nonvanishing magnitude of the “in-plane” (x-y) component of the magnetization h(t), which we denote by h(xy)(t), does not respect the rotational symmetry of the microscopic Hamiltonian \(\hat{{{\mathcal{H}}}(t)\), see Eq. (1). Therefore, ∣h(xy)(t)∣ serves...
A mixed occupation Co/Si was refined considering the basic atomic frameworks of related crystal structures. The symmetry reduction to the space group P-3 (No 147) does not resolve the disorder phenomenon. Finally, the atomic positional parameters were first refined in the preliminary cycles ...
crystals Crystals 2018, 8, 225 2 of 26 the total energy of a many-particle system, i.e., the sum of the potential and kinetic energy, needs to be calculated solving the time-independent Schrödinger equation [16] HΨ = EΨ (1) with H as the Hamiltonian operator, at least in ...
