  In this work, we have investigated the coexistance of volatile and
non-volatile memristive effects in epitaxial phase-separated
La$_{\text{0.5}}$Ca$_{\text{0.5}}$MnO$_{3}$ thin films. At low temperatures (50
K), we observed volatile resistive changes arising from self-heating effects in
the vicinity of a metal-to-insulator transition. At higher temperatures (140 K
and 200 K) we measured a combination of volatile and non-volatile effects
arising from the synergy between self-heating effects and
ferromagnetic-metallic phase growth induced by an external electrical field.
The results reported here add phase separated manganites to the list of
materials which can electrically mimic, on the same device, the behavior of
both neurons and synapses, a feature that might be useful for the development
of neuromorphic computing hardware
