Magnetic features in REMeO3 perovskites and their solid solutions (RE=rare-earth, Me=Mn, Cr)

Magnetic hysteresis displacement, thermal inversion of the magnetization, hysteresis loops jumps and crossing branches of hysteresis loops at low magnetic fields are reviewed. Most of these phenomena have been observed in magnetic oxide systems, particularly in perovskite-type manganites and chromites. The paper takes into account structural considerations and different geometrical parameters, such as volume or thin layers.

► Review of both spin reversal phenomena thermal and displacive.
► Study of the crossing branches of the magnetic hysteresis loops.
► Review of the behavior of some stepped hysteresis loops.
