Scanning probe microscopy was used to create and to detect local bias induced charged states in La0.89Sr0.11MnO3 single crystals at room temperature. The lifetime of these nonequilibrium states exceeds 100 h. These bias induced states display also a ferroelectriclike hysteresis with piezoelectric contrast reversed by the applied field. Such states showing reversible multifunctional properties are attractive for modern semiconductor technology with its focus on nonvolatile random-access memories.
