On the spontaneous magnetization of two-dimensional ferromagnets
D. Pescia, A. Vindigni
Ferromagnetism is typically discussed in terms of the exchange interaction and magnetic anisotropies. Yet real samples are inevitably affected by the magnetostatic dipole-dipole in…
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…
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…
One-dimensional Ising ferromagnet frustrated by long-range interactions at finite temperatures
F. Cinti, O. Portmann, D. Pescia +1
We consider a one-dimensional lattice of Ising-type variables where the ferromagnetic exchange interaction J between neighboring sites is frustrated by a long-ranged anti-ferromagn…
