Exchange energy. The phenomenon whereby individual atomic magnetic moments will attempt to align all other atomic magnetic moments within a material with. We report here the electronic structure calculations of the magnetic moment, magneto- crystalline anisotropy energy (MAE), and density of states (DOS) of. Exchange energy. The magnetic moment of a bulk material is the sum of all of its atomic moments. The atomic moments' interactions. In all calculations, structural parameters and ionic positions are allowed to relax. In Table 1a we give the GGA energies (per magnetic unit cell containing. For any realistic magnetic system requiring a spin Hamiltonian defined in terms of various spin exchange parameters, the energy-mapping analysis based on DFT. The Institute of Physics (IOP) is a leading scientific society promoting physics and bringing physicists together for the benefit of all. It has a worldwide. An orbital- and energy-resolved decomposition of the exchange coupling suggests that an increased partial occupancy of eg orbitals near the. With a proper choice of four different magnetic states, a single formula governs all elements of the exchange interaction matrix for any. Depending on the energy density introduced by the external magnetic field, εext, the modeled stack can relax into different equilibrium states. magnetic moments are given in table 1. Comparison of the calculated film formation energies for various Ni atom positions (ontop, bridge, fcc) on Cu().
