Crystal smaller than a grain of sand breaks physics rules, regains superconductivity at 70 Tesla
SMRTR summary
Austrian scientists have cracked the mystery of uranium ditelluride (UTe2), a superconductor that loses its zero-resistance state at 10 Tesla but bizarrely regains it at 40–70 Tesla. By "wiggling" sand-grain-sized samples in pulsed magnetic fields, they discovered strong magnetic fluctuations act as electron "glue," enabling this rare reentrant superconductivity.
