Vertex energies calculated using OOMMF simulations. We have taken the value of MS at the temperature where the string propagation occurs for each set of samples. These energies are plotted in (a) the high magnetization sample where MS was taken at 503 K and (b) for the low magnetization sample where MS was taken at 433 K. (c) The difference in energy between the lowest energy vertex, type 1, and the other vertex types, E i − E1 for the high magnetization sample (open symbols) and the low magnetization sample (filled symbols), for the three lattice spacings studied a = 450, 500 and 600 nm.
