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

The investigation of the spin dynamics in a series of chemically designed europium(II)-based endohedral metallofullerenes (EMFs) is reported. As a unique structural difference, metal-cage binding site can be introduced in EMFs and is demonstrated to play a key role in determining rigidity of the three low-energy metal-displacing vibrations and the spin-lattice relaxation times (T 1).

The spin relaxation times in the ground state and the first excited state were measured to be 1.0 and 0.6 ns, respectively, without the disturbance of inhomogeneous broadening. The measured spin relaxation time decreases rapidly from 1.1 ns at 10 K to 200 ps at 130 K.

1 relaxation (longitudinal): Spin-lattice relaxation occurs by transfer of energy to the surroundings (heat); dipolar coupling to other spins. Results in recovery of M z to 63% of original value. • T 2 relaxation (transverse): Spin-spin relaxation occurs by redistribution of energy among various spins of the system. Results in recovery of M.

The interplay between superconductivity and spin-orbit coupling (SOC) is at the centre of intensive research efforts as it can generate a variety of unique phenomena such as the occurrence of triplet superconductivity, for instance 1.Recently, hybrid nanostructures involving a superconductor in proximity to a semiconducting nanowire with a strong SOC have been proposed as an ideal system to.

Iridates with the 5$d^4$ electronic configuration have attracted recent interest due to reports of magnetically-ordered ground states despite longstanding expectations that their strong spin-orbit coupling would generate a $J = 0$ electronic ground state for each Ir$^ {5+}$ ion. Relaxation mechanism (e.g. unpaired electron spin) One of the spins (say I) is saturated by rf irradiation (e.g. 13C-{1H} experiment) • Otherwise, bi-exponential relaxation 13C relaxation under proton decoupling • Spin-tattice relaxation rate (T1-1) depends on the molecular size (τc) and the magnetic field • For rapidly-moving systems (small. Scalar coupling is the isotropic part (independent on the molecular orientation) of the J coupling. The J coupling arises due to indirect interaction between the two nuclear spins, where the interaction is mediated by the electrons participating in the bond(s) connecting the nuclei. Magnitude of J coupling is typically larger when nuclei are.

Dipolar interaction causes spin relaxation, but it's not the only way of relaxation.... That is the same than in solid state, but much weaker, that is generally measured as an extra part to the J-Coupling. Very long range measurement made possible using pulsed EPR. Pulsed EPR experiment could allow to measure very long distances ( 70 Angstrom.

First-principles calculations of the essential spin-orbit and spin relaxation properties of phosphorene are performed. Intrinsic spin-orbit coupling induces spin mixing with the probability of ${b}^{2}\ensuremath{\approx}{10}^{\ensuremath{-}4}$, exhibiting a large anisotropy, following the anisotropic crystalline structure of phosphorene. For realistic values of the momentum relaxation times. We investigate the longitudinal spin relaxation arising due to spin-flip transitions accompanied by phonon emission in quantum dots where the strength of the Rashba spin-orbit coupling is a random function of the lateral (in-plane) coordinate on the spatial nanoscale. In this case the Rashba contribution to the spin-orbit coupling cannot be completely removed by applying a uniform external.

The nuclear relaxation time) that one can explore many different dynamical regimes.2 For instance, one dynamical regime is the case where the coupling V is large, termed the adiabatic limit. In this limit, the system evolves as if on a single electronic potential sur-face; one can invoke standard classical transition state theory (TST). Spin-spin 10, spin-phonon 11, and spin-impurity scatterings, all contribute to spin relaxation, but spin-phonon scattering sets the intrinsic material limitation and is typically the dominant mechanism at room temperature 1. Further, spin-phonon relaxation arises from a combination of spin-orbit coupling (SOC) and electron-phonon. Dipolar Coupling vs. J-Coupling, 2 Despite the very different origins of these two-spin mutual couplings, they can both be described by second-rank tensors which are axially symmetric (i.e., J2 is not the same as Jz; same for RDD) The major difference between these tensors is that the J-tensor is not.

J-Coupling and Relaxation • Because J is unchanged with molecular tumbling, J-coupling typically does not contribute to relaxation. A little foreshadowing… • However, there are a few cases where J can become "effectively" time-varying.- Case 1: the S spin is engaged in chemical exchange- Case 2: the T 1 of the S spin itself is << 1/J.. Abstract. The control of spins and spin to charge conversion in organics requires understanding the molecular spin-orbit coupling (SOC), and a means to tune its strength. However, quantifying SOC.
