Local Charged States in La0.89Sr0.11MnO3 Single Crystals
Abstract
We report the direct evidence of the possibility of charge segregation in manganites. The high contrast of electric-field-induced local charged states is observed during more than 100 hours at room temperature. These induced states display a piezoelectric response and polar properties. This effect may be an example of a new kind of polar ordering in solid state.
