Spin-orbit-entangled electronic phases in 4$d$ and 5$d$ transition.
The spin-orbit coupling constants (SOCC) in atoms and ions of the first- through third-row transition elements were calculated for the low-lying atomic states whose main electron configuration is [ nd] q ( q = 1-4 and 6-9, n = the principal quantum number), using four different approaches: (1) a nonrelativistic Hamiltonian used to construct multiconfiguration self-consistent field (MCSCF) wave. Spin-orbit coupling (SOC) is crucially important for the correct description of the electronic structure and transport properties of inorganic semiconductors, and for assessing topological properties as in topological insulators. We present a consistent set of SOC parameters for the density-functional based tight-binding (DFTB) method covering the elements throughout the periodic table. The.

We investigate, through first-principles calculations, the electronic band structure-including the spin-orbit coupling-of single-layer M3(THT)2 metal-organic frameworks, where M = Ni, Pt, Cu and Au, and THT is the 1,2,5,6,9,10-triphenylenehexathiol molecule. This MOF family contains, in its electronic structure, spin-orbit gaps that could allow their use in quantum spin Hall effect devices.

Effect of Spin-Orbit Interaction on (4d)3- and (5d)3-Based Transition.
Download PDF Abstract: Complex oxides with $4d$ and $5d$ transition-metal ions recently emerged as a new paradigm in correlated electron physics, due to the interplay between spin-orbit coupling and electron interactions. For $4d$ and $5d$ ions, the spin-orbit coupling, $\zeta$, can be as large as 0.2-0.4 eV, which is comparable with and often exceeds other relevant parameters such as Hund's. We isolate and quantify the spin-relaxation rate caused by Rashba SOC and show its strength is tunable via transverse electric fields.Then we investigate the SOC in graphene coupled to monolayer TMD films. We show that the spin relaxation rate varies linearly with the momentum scattering time and is independent of the carrier type.

Aug 20, 2015 · Origin of spin–orbit coupling. When an electron with momentum p moves in a magnetic field B, it experiences a Lorentz force in the direction perpendicular to its motion F = −e p × B/m and. Den radiative electronic transitions to the ground state. Spin-orbit coupling (SOC), a relativistic effect[33] generated in the electronic structure by the presence of the high nuclear charge of the heavy metal, is responsible for lifting the spin selection rule, such that these transitions become weakly allowed. For. The valence flat bands in transition metal dichalcogenide (TMD) heterobilayers are shown to exhibit strong intralayer spin-orbit coupling. This is reflected in a simple tight-binding model with spin-dependent complex hoppings based on the continuum model. A perpendicular electric field causes interlayer hybridization, such that the effective model.
A spin-orbit playground: surfaces and interfaces of transition metal.
Here we investigate the angular momentum of the primary star, based on Kepler photometry and Keck spectroscopy. The primary star's rotation period is 35.1 +/- 1.0 days, and its projected obliquity with respect to the stellar binary orbit is 1.6 +/- 2.4 degrees. Therefore the three largest sources of angular momentum---the stellar orbit, the.

In the case of many 3d metals, the effect of spin-orbit coupling on the magnetic characteristics of the compound can be neglected, due to the phenomenon of "freezing" of the orbital moment [].However, for compounds containing the Co 2+ ion, generally the model neglecting spin-orbit coupling does not allow us to describe the experimental data, i.e., the orbital moment of Co 2+ cannot be.

Evidence for spin swapping in an antiferromagnet | Nature Physics.
As a family of two-dimensional (2D) layered materials, Transition metal dichalcogenides (TMDCs) MX2 (M=Mo,W; X=S,Se) have been demonstrated to have potential for applications in the field of spintronics because of their strong spin-orbit coupling, spin-splitting with broken inversion symmetry and spin-valley degrees of freedom. In our work, the 2D MX<SUB>2</SUB> were grown using chemical vapor. Until recently, the spin of the electron was ignored in mainstream charge-based electronics. A technology has emerged called spintronics (spin transport electronics or spin-based electronics), where it is not the electron charge but the electron spin that carries information, and this offers opportunities for a new generation of devices combining standard microelectronics with spin-dependent. Transition metal (TM)... Spin-orbit coupling, especially relevant for 4 d and 5 d compounds, can also play an important role and in many cases it works together with electron hopping to suppress magnetic state, although in some situations it can also act in opposite direction. Our results show yet one more nontrivial effect in the rich.

For the spin moment aligned along the a axis (Fig. 3 A and B, S × E = 0), the Rashba-type term cannot act and thus no hybridization would be expected from this form of spin-orbit coupling. In contrast, at the spin reorientation transition where the moment aligns along the b axis (Fig. 3C), the Rashba-like spin-orbit interaction becomes.
