## Description

- description: Volatile resistive switching in correlated-electron systems, characterized
    by an abrupt resistance decrease　under applied current, is crucial for developing
    next-generation electronics. Despite its technological significance, the underlying
    physics remains elusive. Inorganic thin films on substratesthe widely studied
    platform for resistive switchingusually exhibit broad temperature-induced metalinsulator
    transitions (MITs) and substantial heat dissipation. These factors complicate
    the nonlinear thermal effect induced by Joule heating, a key contributor to resistive
    switching, rendering it excessively complex and difficult to decipher. Here we
    investigate a resistive-switched state in the bulk organic conductor (d7-DMe-DCNQI)2Cu,
    which undergoes an extremely sharp first-order MIT and exhibits weak heat dissipation,
    using resistance and 1H-NMR measurements. These extreme conditions make the Joule
    heating effect vivid, allowing us to observe peculiar phenomena, including temperature
    locking to the MIT and ’Inverse Ohm’s law’an inverse proportionality between voltage
    and current. These findings provide fundamental insights into the nonlinear thermal
    effect in resistive switching, offering a pathway to efficient resistive-switching
    technologies.
