Ferroelectric switching versus resistive switching. a,b, Out-ofplane PFM phase (a) and amplitude (b) measurements on a typical gold/cobalt/BTO/LSMO ferroelectric tunnel junction. c, R(Vwrite) for a similar capacitor measured in remanence (Vread¼100 mV) after applying successive voltage pulses of 100 ms. The open and filled circles represent two different scans to show reproducibility.
