On the Theory of the Thermofluctuation Motion of Domain Walls in Nanowires

摘要

Using the Arrhenius law, the thermofluctuation motion of a domain wall in a nanowire in the field of energy barriers formed by magnetic nonuniformities is investigated. The expression for the density of the distribution of the activation energy in the case of the domain wall pinning at magnetic nonuniformities has been obtained. The velocity of the thermally activated motion of the domain wall for certain particular cases of the probabilistic distribution of the activation energy has been estimated.
