Magnetic field sorting of superconducting graphite particles with Tc>400K (2024)
(arxiv.org)
It has been claimed that graphite hosts superconductivity at room temperature, although all efforts to isolate it have been vain. Here we report a separation method that uses magnetic field gradients to sort the superconducting from normal grains out of industrial graphite powders.
