Hysteresis switching loops in Ag-manganite memristive interfaces

Mostrar todas las versiones(3)

Multilevel resistance states in silver-manganite interfaces are studied both experimentally and through a realistic model that includes as a main ingredient the oxygen vacancies diffusion under applied electric fields. The switching threshold and amplitude studied through hysteresis switching loops...
