Stoner–Wohlfarth astroid
text:
In magnetism, the Stoner–Wohlfarth astroid curve is a curve that separates regions with two minima of the free energy density from those with only one energy minimum. It is a geometric representation of the Stoner–Wohlfarth model. This curve is of particular importance as discontinuous changes of the magnetization can take place when crossing it. One important property of the astroid is that tangents to the astroid represent magnetization directions with extremal energy, i.e. either local minima
