Origin of colossal magnetoresistance in LaMnO3 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.

Van der Waals lattice-induced colossal magnetoresistance in Cr2Ge2Te6 thin flakes [PDF]

Nature Communications, 2022
Due to their layered structure, and resulting weak interlayer exchange coupling, van der Waals materials can exhibit distinct behaviour depending on whether the spins are aligned in the plane, or perpendicular.

Colossal electroresistance and colossal magnetoresistance in spinel multiferroic CdCr2S4 [PDF]

Applied Physics Letters, 2010
Colossal magnetoresistance (CMR) and colossal electroresistance (CER) induced by the electric field in spinel multiferroic CdCr2S4 are reported. It is found that a metal-insulator transition in CdCr2S4 is triggered by the electrical field. In magnetic fields, the resistivity ρ of CdCr2S4 responds similarly to that of CMR manganites.
