Notes:
Based on Monte Carlo simulation we study the coercivity of iron nanowire deposited inchemically widened anodic aluminum oxide films. The coercivity is found to depend on thediameter and aspect ratio of the nanowire, and it decreases with increasing nanowire diameter,which is consistent with the experimental result. Two kinds of discretization cells regularglobal-shaped and regular cubic-shaped are used as minimum element. The simulation resultreveals that the regular global-shaped discretization cell allows for more accurate calculated resultwhile comparing to the experimental result than the cubic-shaped discretization cell does. Thesimulated coercivity as a function of temperature with different diameters shows that the data canbe described well by the T-c power-law, and the diameter dependence of the exponent c displays amaximum peak
