Critical Magnetic Relaxation

Critical Relaxation and Critical Exponents 1

Dynamic relaxation of the XY model and fully frustrated XY model quenched from an initial ordered state to the critical temperature or below is investigated with Monte Carlo methods. Universal power law scaling behaviour is observed. The dynamic critical exponent z and the static exponent η are extracted from the time-dependent Binder cumulant and magnetization. The results are competitive to t...

Nuclear Magnetic Relaxation

Proton Magnetic Relaxation in Gases

Measurements of the longitudinal nuclear spin relaxation time, Ti, in molecular gases are analogous to non-resonant absorption measurements; Ti is determined primarily by that part of the spin-lattice interaction which couples free molecular states of the same energy. The contribution to Ti of matrix elements of the spin-lattice interaction between rotational states of different energy is quenc...
