Furthermore, we also obtained strain-induced spin reorientation from in-plane to perpendicular magnetic anisotropy (1.27 meV cell −1) at 4% compressive strain, although the Curie temperature was decreased to 61 K. Under 4% compressive strain, the Curie temperature was slightly larger than that of the pristine CGT, but the magnetic anisotropy. Dysprosium complexes can serve as transverse relaxation (T(2)) agents for water protons through chemical exchange and the Curie spin relaxation mechanism. Using a pair of matched dysprosium(III) complexes, Dy-L1 (contains one inner-sphere water) and Dy-L2 (no inner-sphere water), it is shown that the transverse relaxation of bulk water is predominantly an inner. Thus, the electron relaxation time τ s is calculated to be 9.6 ns. For this system, Eqs. 3 and 10 predict that the contribution of the Curie-spin relaxation mechanism to the overall Γ 2 at 308 K is only 2%, even at a 1 H-frequency of 800 MHz. The relative contribution of the Curie-spin relaxation depends on the size of the system.

Mar 01, 2002 · We assess the potential of obtaining structural constraints from the cross-correlation of Curie spin relaxation with dipolar relaxation mechanisms among methyl proton spins. By theoretical analysis and numerical simulations we characterize the transfer functions describing the interconversion processes of different ranks of multispin order. The 15N-HSQC spectra of low-spin cyano-met-myoglobin and high-spin fluoro-met-myoglobin were assigned and dipole-dipole-Curie-spin cross-correlated relaxation rates measured. These cross-correlation rates originating from the dipolar 1H-15N interaction and the dipolar interaction between the 1H and the Curie spin of the paramagnetic center. The electronic spin-spin relaxation time, T 2, is calculated for Heisenberg ferromagnets in the region immediately above the Curie point. The calculation, which pertains to zero field, predicts that 1/ T 2 diverges as χ T 3/4 where χ T is the isothermal susceptibility.

This new equipment allows students to perform experiments that naturally lead them to an understanding of precession, Curie's Law of paramagnetism, spin-lattice relaxation and even spin-spin coupling. The apparatus lends itself to inquiry based explorations. Its adjustable variables and magnetic resonance signals are all on a human scale.

Curie Spin Relaxation (CSR) CSR in the interaction between the nuclear spin and the static magnetic moment <S z> (the time-averaged electron spin moment) This interaction cannot be modulated by the electron spin relaxation, since <S z> is already an average over the electron spin states The correlation time for this coupling is only determined. The temperature dependence of the relaxation time in spin system is obtained near the Curie temperature and is corresponding with the critical slowing down phenomena. ©1972 The Physical Society of Japan.

Parameters. Irreversibility is a result of relaxation pro-cesses of ariousv origin, like the irreversible movement of domain walls, small hysteresis loop in ferromagnets, spin lattice relaxation in paramagnets, relaxation of su-perparamagnets or ux creep in superconductors. Re-laxation time, or its distribution, may be determined (964). The spin fluctuations possess a steep energy-wave vector relation and are indicative of strong exchange interactions, consistent with the large Curie-Weiss temperature. As the temperature approaches T$_g$ from above, a shift in spectral weight from inelastic to elastic scattering is observed.... a characteristic relaxation rate of the.

[2106.10943] Nuclear spin-lattice relaxation time in UCoGe.

Paramagnetism Curie No explicit temperature dependence is included in the equations for R m and Rim, except for cases where Curie spin relaxation is the dominant term (Section 3.6). In the latter case, Curie paramagnetism has a T x dependence and therefore relaxation depends on T 2. Cross-correlated relaxation caused by the interference of nuclear dipole-dipole interaction and the Curie spin relaxation (DD-CSR cross relaxation) is generalized to treat the case of anisotropic magnetic susceptibility, including the important case where the latter originates from zero-field splitting.

Due to many oxygen-rich hydrophilic groups on its surface, graphene oxide is an essential material from an applicational point of view [ 64 ]. A single Lorentz line can resolve the EPR line. The spin-lattice relaxation rate T 1FID−1 in graphene oxide increases from 19 kHz (52 ms) at 5 K to 6.54 kHz at 240 K (0.153 ms).

The spin-lattice relaxation rate is dominated by this mechanism and has the same value as the above contribution to the line width. The effect of the anisotropy and the external magnetic field on this mechanism is also discussed.

University of Wisconsin–Madison Abstract The electronic spin-spin relaxation time, T~, is calculated for Heisenberg ferromagnets in the region. Spatially resolved low-energy muon spin relaxation spectroscopy investigations, performed as a function of both the muon implantation energy and temperature, demonstrate that a homogeneous long. The kinetic coefficient associated with the domain-wall motion exhibits a critical speeding up close to T c. Damping by longitudinal spin-spin-relaxation within linear walls is proposed to explain this intrinsic phenomenon.
