24. For the simulations, in Ref. the trial new orientation of the magnetic moment was randomly generated inside a cone of angle 0.1 radian. In this study, we have included a slight modification of this procedure, consisting on treating the angle as temperature dependent, following the work of U. Nowak, Phys. Rev. Lett. 0031-9007 10.1103/PhysRevLett.84.163 84, 163 (2000)
25. in the same way as described in D. Serantes, J. Appl. Phys. 0031-9007 10.1103/PhysRevLett.84.163 108, 073918 (2010).
26. It is worth to mention that this alternative was used because we consider it more realistic (it results in larger oscillations at higher temperatures), but the same features of critical field and oscillations appear if using a constant cone angle of 0.1 radian.
