LK-99 shows resistance-switching instead of superconductivity

The I-V curve indicates switching from an ultralow but nonzero resistance to a higher resistance, at a given current level, which is lower for higher temperature.

Rather than superconductivity, this looks like the RESET phenomenon in unipolar RRAM. It could be a correlated-electron phenomenon related to an insulator-metal transition.
