Abstract
The electric pulses induced responses of (V0.99Cr0.01)2O3 in hysteresis temperature range have been investigated. We observed that multiple nonvolatile resistance states can be tuned by electric pulses due to the first-order metal to insulator phase transition, and, moreover, a reset can be realized by joule heating conveniently. Our calculations showed that the potential difference near the metal-insulator boundaries but close to the insulating side is remarkably larger, driving the resistance jumps. The multi-resistance states or the nonvolatile resistance properties excited simply by electric pulses have profound significance for the explorations of solid-state devices.
