Variations in Local Oscillatory Dynamics in Strained LSMO Thin Films, Observed in Non Equilibrium Transport Studies, for Brain Networks
Abstrak
ABSTRACT Strong correlation effects in transition metal oxides and their sensitivity to external stimuli in driving phase transitions have been widely explored. However, the richness of the metastable and coexisting quantum states beyond the phase transition temperature is less explored. We employ a highly strained manganite film on a twinned substrate of LaAlO3 and show that the cumulative effect of such structural disorder leads to temperature‐driven subtleties in the orbital hybridization of the coexisting ground states. This drives the film to electrical instabilities and the associated non linear transport leads to oscillatory dynamics, mimicking neurons with frequencies that are within the range of frequencies associated with brain waves. Our findings open up possibilities for on‐demand tailoring of such devices for applications in brain‐computer interfacing.
