Strong Spin-Phonon Coupling in Two-Dimensional Magnetic.

The linewidth notably increases (or life time decreases) below the magnetic ordering temperature implying a coupling of the lattice with magnetic degrees of freedom through spin-phonon coupling. It is to be noted here that the 5 d oxides (Ir 4+ ; 5 d 5 ) show notable spin-phonon coupling as the spatially extended 5 d orbitals give rise to a large orbital overlap [ 10 , 23 ]. Oct 13, 2015 · The comparison of the experimental and first-principles calculated phonon spectra highlights unambiguously a spin-phonon coupling character in YMnO 3. This is further supported by the pronounced differences in the magnetic and non-magnetic phonon calculations.

Spin‐Phonon Coupling and Slow‐Magnetic Relaxation in Pristine.

Abstract. Recently, spin-phonon coupling (SPC) has gained considerable attention especially in two-dimensional (2D) materials. Herein, density-functional theory is used to investigate the SPC effect in CrSBr, a recently fabricated 2D magnetic semiconductor. It is found that the phonon vibrations are strongly dependent on the spin ordering. We probe this coupling as a remarkably large shift of phonon frequencies and the appearance of new phonons. The spin–phonon coupling is absent for the magnetic ordering of iron alone but emerges. CALL TODAY: (845) 201-1691 It is a big problem when the washer or dryer goes out.

Emerging spin–phonon coupling through cross-talk of two.

1 Spin-phonon coupling is an interesting phenomena, especially, in the case of multiferroic materials. Its origin is said to be the exchange interaction of magnetic ions. In that case, any magnetic materials should have significant spin-phonon coupling. But we never see this phenomena in all magnetic materials. Here, we provide the first experimental evidence for a strong spin-phonon coupling between a single molecule spin and a carbon nanotube resonator, ultimately enabling coherent spin manipulation and quantum entanglement.

Spin-phonon coupling in antiferromagnetic nickel oxide.

We present an unconventional mechanism for Raman scattering of phonons, which is based on the linear magnetoelastic coupling present in non-Kramers magnetic ions. This provides a direct coupling of Raman-active phonons to the magnet's quasiparticles. We propose to use this mechanism to probe the emergent magnetic monopoles, electric charges, and photons of the emergent quantum electrodynamics. Spin-phonon (SP) coupling.
