Heterogeneity in mixed-valence manganites

Recent studies focus on the static and dynamic character of microscale electronic phase segregation in manganese perovskites, along with associated magnetic polaron effects. Interest in the magnetoresistance of manganese perovskites has shifted from the colossal magnetoresistance observed near the Curie temperature to low-field magnetoresistance, a micromagnetic phenomenon found in many sorts of granular material.
