Support near field outside of magnetic domains
When probing magnetic domains in a layer with magnetic anisotropy perpendicular to the plane, the interaction of neutrons with the magnetic field above the sample surface should not be neglected.
The potential way to do it is to compute magnetic field distribution produced by domains using OOMMF or MUMAX. Then add "vacuum" layers on top of the sample, split it to domains and set magnetization from micromagnetic simulations.
