High-performance ferroelectric nonvolatile memory based on Gd-and Ni-codoped BiFeO 3 films

BiFeO (BFO), Bi Gd FeO (BGFO) and Bi Gd Fe Ni O (BGFNO) films are epitaxially grown on 0.7 wt% Nb-SrTiO (NSTO) substrates. The strong ferroelectric property in BGFNO film is confirmed by piezoresponse force microscopy (PFM) and polarization voltage ( - ) measurement. It is also found that the Au/BGF...
