Finite temperature phase diagram of ultrathin magnetic films without external fields
Santiago A. Pighin, Orlando V. Billoni, Sergio A. Cannas
We analyze the finite temperature phase diagram of ultrathin magnetic films by introducing a mean field theory, valid in the low anisotropy regime, i.e., close to de Spin Reorienta…
T=0 phase diagram and nature of domains in ultrathin ferromagnetic films with perpendicular anisotropy
Santiago A. Pighin, Orlando V. Billoni, Daniel A. Stariolo +1
We present the complete zero temperature phase diagram of a model for ultrathin films with perpendicular anisotropy. The whole parameter space of relevant coupling constants is stu…
Domain walls, canted states and stripe width variation in ultrathin magnetic films with perpendicular anisotropy
Santiago A. Pighin, Orlando V. Billoni, Daniel A. Stariolo +1
Stripe width variation in ultrathin magnetic films is a well known phenomenon still not well understood. We analyze this problem considering a 2D Heisenberg model with ferromagneti…
The Spin Reorientation Transition and Phase Diagram of Ultrathin Ferromagnetic Films
Marianela Carubelli, Orlando V. Billoni, Santiago Pighin +3
We show results from Monte Carlo simulations of a two dimensional Heisenberg model for ultrathin films with perpendicular anisotropy. A complete phase diagram is obtained as a func…
Phase diagram of an Ising model for ultrathin magnetic films
S. A. Pighin, S. A. Cannas
We study the critical properties of a two--dimensional Ising model with competing ferromagnetic exchange and dipolar interactions, which models an ultra-thin magnetic film with hig…
