Magnetization Dynamics of a Material with Spin Triplet States Affected by a Weakly Varying Field and Spin-Lattice Interaction in a Zero Constant Field

Abstract

The goal of this researchchanged into to have a look ateachnormal and abnormal dynamics of spin-triplet states (STSs) withinside the case of one-photon and one-magnon interactions with the various magnetic subject and the lattice, respectively. The anisotropic normal dynamics of STSs of molecular unmarried crystals in 0steady and vulnerablevarious magnetic fields (weak spotapproach the absence of saturation on theconsistentnation and of the nutation on the pulse EPR) directed alongside the molecular axes, changed into analytically investigated. The equations have been derived for the unfastenedmovement of the pattern magnetization, describing its linear oscillations alongside that molecular axis, alongside which its nonzero preliminarypricechanged into created. The tensor of the consistent-nation dynamical susceptibility to the varioussubjectchanged into found. The end result of the motion of a quick MW pulse on STS changed into analytically described, containing a periodic dependence at the pulse period and its detuning. The anisotropic abnormal dynamics of electron spin-lattice relaxation (SLR) at its one-phonon mechanism changed into investigated without the excessive temperature approximation over the phonon temperature; the SLR costs of the separate transitions of STS have been calculated; the corresponding SLR possibilitieshave been written withinside the form, which supposes the fractal dimensionality d of a lattice; the consequences with d=4/three agreed nicely with the experimental statistics in STS of the buried tryptophan of ribonuclease
