YbSb2 superconductor found to break time-reversal symmetry

Original: YbSb2, a "plain" Type I superconductor, has shattered expectations. Scientists found it spontaneously generates its own

Scientists report that YbSb2, long considered an ordinary Type I superconductor, spontaneously generates its own magnetic field, breaking time-reversal symmetry — a first for this class of material. The finding challenges assumptions that such materials behave conventionally and is prompting researchers to re-examine other 'plain' superconductors for unexpected internal physics.

Why now: A surprising discovery overturning textbook assumptions about ordinary superconductors is drawing attention from the physics community
