论文摘要
在这项工作中，我们研究了外在相位分离的la $ _ {\ text {0.5}} $ ca $ _ {\ text {0.5}} $ mno $ _ {3} $ thin $ thin films。在低温（50 K）下，我们观察到由金属对构造器过渡的附近自动加热效应引起的挥发性电阻变化。在较高的温度（140 K和200 K）下，我们测量了由外部电场引起的自加热效应与铁电磁 - 金属相生长之间的协同作用的挥发性和非挥发性效应的组合。此处报告的结果将相位分离的锰矿添加到可以在同一设备上电气模仿神经元和突触的行为的材料列表中
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
