Origin of colossal magnetoresistance in LaMnO 3 manganite [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance Magnetoresistance is the change of resistance in the presence of an external magnetic field. In rare-earth manganite compounds, this change is orders of magnitude stronger than usual and it is promising for developing new spintronic and electronic devices. The colossal magnetoresistance (CMR) effect has been observed
