摘要

Although the thermistor and metal to insulator transition bi-functionalities were discovered for rare-earth nickelates(RENiO3),the electronic stability in their correlated transports under impulse voltage or magnetic field remain as open questions.Herein,we demonstrate the thermistor transportations of the electron correlated rare-earth nickelates under impulse direct current voltage and in magnetic environment.The insulating phase of RENiO3 shows zero crossing linear Ⅰ-Ⅴ characters,indicating their stable electronic resistance is independent of the imparted voltage up to 10 V and pulse width down to 1 μs,in spite of their sensitive electronic structures to polarizations.In addition,the high electronic stability associated with the thermistor transportation of RENiC3 is also demonstrated in magnetic fields up to 9 T(i.e.,MR＜ 0.2％).The high electronic stability further paves the way to applying RENiO3 as a broad temperature range thermistor in temperature sensing or circuit protections for correlated electronics.
