  The electric pulse-induced responses of 1T-TaS2 and 1T-TaS1.6Se0.4 crystals
in the commensurate charge-density-wave (CCDW) phase in the hysteresis
temperature range have been investigated. We observed that abrupt multiple
steps of the resistance are excited by electric pulses at a fixed temperature
forming multi metastable like states. We propose that the response of the
system corresponds to the rearrangements of the textures of CCDW domains and
the multi-resistance states or the nonvolatile resistance properties excited
simply by electric pulses have profound significance for the exploration of
solid-state devices.
