Descripción
Magnetic-field-driven domain wall motion in an ultrathin Pt / Co ( 0.45    nm ) / Pt ferromagnetic film with perpendicular anisotropy is studied over a wide temperature range. Three different pinning dependent dynamical regimes are clearly identified: the creep, the thermally assisted flux flow, and the depinning, as well as their corresponding crossovers. The wall elastic energy and microscopic parameters characterizing the pinning are determined. Both the extracted thermal rounding exponent at the depinning transition, ψ = 0.15 , and the Larkin length crossover exponent, ϕ = 0.24 , fit well with the numerical predictions.
