Colossal magnetoresistance in La-Ca-Mn-O
Metals and Materials, 1997ABSTRACTVery large increase in electrical conductivity by several orders of magnitude is obtained when an external magnetic field is applied to the colossal magnetoresistance (CMR) materials such as La-Ca-Mn-O. The magnetoresistance is strongly temperature-dependent, and exhibits a sharp peak below room temperature, which can be shifted by adjusting ...

Ferromagnetism and Colossal Magnetoresistance from Phase Competition
Physical Review Letters, 2000We report a multicomponent theory for the coexistence of charge ordering (CO), and antiferromagnetic (AFM) and ferromagnetic (FM) spin ordering. This kind of state is invoked for manganites by Moreo et al., Science 283, 2034 (1999) and observed in recent experiments. We show that doping an AFM or CO state always generates a FM component.
