MnBi4Te7 single crystals show a field-cooling-induced exchange bias with a training effect that also shifts the anomalous Hall loops, attributed by the authors to Mn-Bi antisite defects.
This will uncover pos- sible phase coexistence, spin reorientation transitions, and field-sensitive behavior

Intertwined magnetic phase driven exchange bias and its impact on the anomalous Hall effect in MnBi$_4$Te$_7$
MnBi4Te7 single crystals show a field-cooling-induced exchange bias with a training effect that also shifts the anomalous Hall loops, attributed by the authors to Mn-Bi antisite defects.
