Spin magnetization density

This method has been used for the reconstruction of charge densities from X-ray data [1-3], for maps of nuclear densities from unpolarized neutron data [4-6] as well as for distributions of spin (magnetization) density [7-9].The density... 

Fig. 11.13 Schematic ZGNR-based spin-valve device with parallel tmd anti-parallel spin configurations and the corresponding spin-magnetization density isosurfaces. The blue boxes represent ferromagnetic electrodes to control spin polarization of the ZGNR device and the red arrows indicate the directions of applied magnetic fields. In the isosurfaces, red/blue color denotes up/down spin and a ZGNR skeleton is drawn in green color (Reproduced from Ref [14] with kind permission of Nature Publishing Group)...

In the limit P —> 1, the a-polarized component of the magnetic scattering from a helix depends only on the spin magnetization density, I oc while the r-polarized component depends on the sum of the orbital and spin densities I oc (i + sY- Thus, it is in this sense that the spin and orbital contributions to the total moment may be separated. Semi-quantitative experiments to demonstrate these ideas in a helix have been performed on Ho (Gibbs et al. 1988, Gibbs et al. 1991). Both jt- and a-polarized scattered beams were observed. It was demonstrated that the nr-component is dominant, consistent with the large orbital moment in Ho, and that the Q dependence of the orbital and spin form... 

In this section, we describe how to partition the spin density distribution between atoms in a material. This partitioning is important for understanding the properties of magnetic materials. The spin magnetization density, m r), is computed by summing the spins of all electrons at position r and dividing by the spin magnitude of an individual electron ... 

Spin partitioning is the process of assigning a spin magnetization density, mA rA, to each atom in the system such that...
