Abstract :
The velocities of magnetic domain wall displacements during reversal magnetization in a nano-wire were simulated as a function of impurity and defect densities in the host spin lattice, by using Monte Carlo method. The magnetic domain wall displacement velocity was enhanced for the clusters with defects and it was suppressed for ones with impurities.
