Abstract
Abstract
We investigate the switching kinetics of oxygen vacancy (Ov) diffusion in
La(5/8-y)Pr(y)Ca(3/8)MnO(3)-Ag (LPCMO–Ag) memristive interfaces by performing experiments
on the temperature dependence of the high resistance state under thermal cycling. Experimental
results are well reproduced by numerical simulations based on thermally activated Ov diffusion
processes and fundamental assumptions relying on a recent model proposed to explain bipolar
resistive switching in manganite-based cells. The confident values obtained for activation
energies and the diffusion coefficient associated to Ov dynamics constitute a validation test
for both model predictions and Ov diffusion mechanisms in memristive interfaces.
