Abstract

Bulk polycrystalline La_0.8Li_0.2MnO₃ is found to switch between a low-resistance state and a high-resistance state on thermal cycling. The low-temperature, high-resistance state exhibits strong electroresistance whereas the high-temperature, low-resistance state does not. The change in resistance between the two distinct states is of two orders of magnitude. It is proposed that the observed metastability may serve as the basis for resistive thermal-switching devices.
