Critical exponents and scaling invariance in the absence of a critical point
N. Saratz, D. A. Zanin, U. Ramsperger +3
The paramagnetic-to-ferromagnetic phase transition is believed to proceed through a critical point, at which power laws and scaling invariance, associated with the existence of one…
(Ir-)Reversibility and thermal equilibrium in magnetic domain pattern formation in ultra-thin ferromagnetic films
N. Saratz, U. Ramsperger, A. Vindigni +1
We investigate the details of pattern formation and transitions between different modulated phases in ultra-thin Fe films on Cu(001). At high temperature, the transitions between t…
A Scaling Hypothesis for Modulated Systems
O. Portmann, A. Goelzer, N. Saratz +3
We propose a scaling hypothesis for pattern-forming systems in which modulation of the order parameter results from the competition between a short-ranged interaction and a long-ra…
Stripe width and non-local domain walls in the two-dimensional Dipolar Frustrated Ising Ferromagnet
Alessandro Vindigni, Niculin Saratz, Oliver Portmann +2
We describe a novel type of magnetic domain wall which, in contrast to Bloch or Neel walls, is non-localized and, in a certain temperature range, non-monotonic. The wall appears as…
