|Title:||Nuclear Spin-lattice Relaxation Due To Dissipative Domain Walls|
|Author:||Villares Ferrer A.|
|Abstract:||The influence of the dissipation motion of domain walls in the nuclear spin lattice relaxation rate was studied as a function of the external magnetic field and the temperature. The soliton momentum was coupled to the momentum of the magnon thermal bath. The interactions resulted in a Brownian-like motion for the soliton centre of mass, characterized by a temperature and field-dependent diffusion and damping constants. The soliton dynamics of the double sine-Gordon (DsG) equation was demonstrated as diffusive and damped.|
