Optimization of the multi-mem response of topotactic redox LaSrMnCoO
W. Román Acevedo, M. H. Aguirre, C. Ferreyra +6
Memristive systems emerge as strong candidates for the implementation of Resistive Random Access Memories (RRAM) and neuromorphic computing devices, as they can mimic the electrica…
Origin of multistate resistive switching in Ti/manganite/Si/Si heterostructures
W. Román Acevedo, C. Acha, M. J. Sánchez +2
We report on the growth and characterization of Ti/Mn/Si/n-Si memristive devices. We demonstrate that using current as electrical stimulus unveils an…
Thermal effects and switching kinetics in silver/manganite memristive systems: Probing oxygen vacancies diffusion
P. Stoliar, M. J. Sánchez, G. A. Patterson +1
We investigate the switching kinetics of oxygen vacancies (Ov) diffusion in LPCMO-Ag memristive interfaces by performing experiments on the temperature dependence of the high resis…
Asymmetric pulsing for reliable operation of titanium/manganite memristors
F. Gomez-Marlasca, N. Ghenzi, P. Stoliar +4
We present a pulsing protocol that significantly increases the endurance of a titanium-manganite interface used as a binary memory cell. The core of this protocol is an algorithm t…
Anisotropic profiles in the spin polarization of multichannel semiconductor rings with Rashba spin orbit coupling
L. E. Segura, M. J. Sánchez
We investigate the spin accumulation effect in eccentric semiconductor multichannel rings with Rashba spin-orbit interaction and threaded by a magnetic flux. Due to the finite ecce…
Magnetic flux induced spin polarization in semiconductor multichannel rings with Rashba spin orbit coupling
G. S. Lozano, M. J. Sánchez
We show that a finite magnetic flux threading a multichannel semiconductor ring induces spin accumulation at the borders of the sample when the Rashba spin-orbit interaction is tak…
