Researchers realize a tunable asymmetric hysteresis loop

A research team led by Prof. QU Zhe discovered a way to control the magnetic reversal in Co3Sn2S2, a Weyl semimetal, by adjusting the maximum external magnetic field (Hmax) and thermal history. This finding explains the asymmetric hysteresis loop in Co3Sn2S2, different from the usual exchange bias effect.
