Electronic and magnetic stability in correlated transportations of rare-earth nickelate perovskites

Although the thermistor and metal to insulator transition bi-functionalities were discovered for rareearth nickelates(RENiO_3),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 RENiO_3 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 to1 us,in spite of their sensitive electronic structures to polarizations.In addition,the high electronic stability associated with the thermistor transportation of RENiO_3 is also demonstrated in magnetic fields up to 9 T(i.e.,MR0.2%).The high electronic stability further paves the way to applying RENiO_3 as a broad temperature range thermistor in temperature sensing or circuit protections for correlated electronics.
