I'm working with the Stoner-Wohlfarth model with 5 energy terms and I want my system to evolve into a larger system with more possibilities of interaction (dipole interaction) and with different anisotropies from different angles ... It is possible to make Stoner's model -Wohlfarth (coherent rotation of magnetization) in a micromagnetic model? Any possibility or solution to this case?
Basically you can keep the microscopic dipoles aligned if you artificially increase exchange interaction. Exchange keeps neighbouring dipoles oriented in the same direction. But there will be always small deviation - because exchange is quadratic in small deviation and thus small deviations carries small to second power = very small energy contribution. In this sense you will never get "perfectly aligned" elementary moments in the micro-magnetic simulation.
