Query: Spatially extended nature of resistive switching in perovskite oxide
  thin films   We report the direct observation of the electric pulse induced
resistance-change (EPIR) effect at the nano scale on La1-xSrxMnO3 (LSMO) thin
films by the current measurement AFM technique. After a switching voltage of
one polarity is applied across the sample by the AFM tip, the conductivity in a
local nanometer region around the AFM tip is increased, and after a switching
voltage of the opposite polarity is applied, the local conductivity is reduced.
This reversible resistance switching effect is observed under both continuous
and short pulse voltage switching conditions. It is important for future
nanoscale non-volatile memory device applications.
