Decisive role of mixed-valence structure in colossal dielectric constant of LaFeO3

The role of mixed-valence structure in colossal dielectric constant (CDC) behavior has been investigated in LaFeO 3 ceramics by tuning the ratio of Fe 2+ /Fe 3+ through substituting Al for Fe. The ratio of Fe 2+ /Fe 3+ is decreased gradually from 1.0 to 0.0 by increasing the concentration of Al 3...
