Experiment geometry

For experiments in the mrfmsim, two experimental geometry are used: “hangdown” and SPAM (springiness preservation by aligning magnetization). The two geometry are shown in the figure below.

In the “hangdown” geometry, the sample surface is in the \(xy\)-plane, the cantilever oscillates in the \(x\)-direction. In the SPAM geometry, the sample surface is in the \(xz\)-plane, and the cantilever oscillates in the \(x\)-direction. The external field for both geometries is applied in the \(z\)-direction.
