Study Of Spin-Lattice Relaxation Rates In Solids:Lattice-Frame Method Compared With Quantum Density-Matrix Method, And Glauber Dynamic

CommitteeClay, Rudolf T.
The spin-lattice relaxation rates are calculated for a rigid magnetic spin cluster in an elastic medium in the presence of a magnetic eld using the lattice-frame method. This rate is then compared with both the rate calculated using the quantum mechanical densitymatrix method and with the Glauber dynamics. These calculation results are used in the contribution of various heat baths, such as a phonon bath in various dimensions or a fermionic bath, to transition rates that enter into dynamic Monte Carlo simulations of molecular magnets and nanomagnets.
