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…
