Spin memory and spin-lattice relaxation in two-dimensional hexagonal crystals
نویسندگان
چکیده
We propose a theory of spin relaxation of electrons and holes in two-dimensional hexagonal crystals such as atomic layers of transition-metal dichalcogenides (MoS2, WSe2, etc.). We show that, even in intrinsically defect-free crystals, their flexural deformations are able to generate spin relaxation of carriers. Based on symmetry analysis, we formulate a generic model for spin-lattice coupling between electrons and flexural deformations and use it to determine temperatureand material-dependent spin lifetimes in atomic crystals in ambient conditions.

Magnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...

Liquid crystals are composed of flexible organic molecules and capable of forming different ordered structures in their mesophases. Nuclear spin relaxation [1], [2] is a powerful technique that provides useful information on the molecular dynamics of liquid crystals. There are collective director fluctuations, molecular reorientation and internal rotations in flexible end chains. Recently inter...

Electron paramagnetic resonance of Mn2+ and Gd3+ in single crystals of Pr2Co3(N03)i2 • 24 H2O has been studied at X-band at 305 and 77 K. Mn2+ substitutes at two types of Co2 f sites whereas Gd3 substitutes at the single type of Pr3+ site in the lattice. The spin-Hamiltonian parameters have been evaluated. Observation of resolved Mn2+ and Gd3+ spectra at 305 K and their broadening on lowering t...
متن کاملInversion of Spin Signal and Spin Filtering in Ferromagnet|Hexagonal Boron Nitride-Graphene van der Waals Heterostructures.
Two dimensional atomically thin crystals of graphene and its insulating isomorph hexagonal boron nitride (h-BN) are promising materials for spintronic applications. While graphene is an ideal medium for long distance spin transport, h-BN is an insulating tunnel barrier that has potential for efficient spin polarized tunneling from ferromagnets. Here, we demonstrate the spin filtering effect in ...

In this paper a new optical channel drop filter (CDF) based on two dimensional (2-D) photonic crystals (PhC) with hexagonal shaped structure is proposed and numerically demonstrated by using the finite-difference-time-domain (FDTD) and plane-wave-expansion (PWE) techniques. Photonic crystals (PhCs) are artificial dielectric nanostructure materials in which a periodic modulation of the material ...
