The figure at your introduction shows the case of a disk with double vortex. Does your analytical model explain this state? If not, which kind of magnetic model would(will) you use for having the curve in the phase diagram for this double vortex?

I really like your poster

How did you obtain the phase diagram? In our case CoNi has been used with other purposes (https://doi.org/10.1016/j.ijhydene.2019.11.133)

The results of the analytical model that I show do not explain the state of the double vortex. Currently, I'm calculating the total energy in the double vortex state. I'm using a solitonic magnetization model, this model depends on different geometric parameters, for example, eccentricity, central core radius, etc.

To obtain the phase diagram, a magnetization model is provided for each configuration. The expressions of the energies in each state of magnetization are determined (shown on the poster). Subsequently, a minimization process is carried out as a function of the geometric parameters. Finally, the transition line is obtained by equating the energies of each magnetic configuration.
