We had established that the non-monotonic magnetic relaxation appeared, when two or three magnetic fields, switching between stable magnetization states, coincide with each other, in Pt/Co/Ir/Co/Pt synthetic ferrimagnets with perpendicular magnetic anisotropy. Switching fields between stable magnetization states depend on sum of exchange interlayer energy, Zeeman energy and magnetization reversal energy barrier of each layer. This total energy depends on layers thickness and temperature. We had shown that with choose of temperature and free layer thickness we can achieve double or triple points on energy states diagram, which is reason of nonmonotonic magnetization relaxation.
