Abstract

In this study, the pulse-voltage-driven dynamical switching of perpendicular exchange bias in a Pt/Co/Au/Cr2O3/Pt thin film observed at pulse amplitudes exceeding the DC switching threshold is investigated. The switching time decreases with increasing pulse amplitude, reaching values below 10 ns at an amplitude two times higher than the above threshold. Conversely, several hundreds of nanoseconds is required for switching at amplitudes close to the threshold, suggesting that the switching mechanism is dominated by the motion of magnetic domains of the antiferromagnetic layer.
