Time-Resolved Reversal of Spin-Transfer Switching in a Nanomagnet

Key Points

• This research aims to investigate the magnetization reversal in nanomagnets induced by spin-transfer effects.
• Time-resolved measurements were conducted on spin-valve nanomagnetic junctions under pulsed current bias.
• Landau-Lifshitz-Gilbert equation was utilized including spin-transfer-induced corrections and Langevin field.
• Model calculations were compared with experimental results to understand magnetization reversal.
• Excitation from spin-transfer induced magnetization reversal was confirmed, aligning with theoretical models.
• Time-resolved measurements demonstrated the dynamics of reversal in response to pulsed current bias.
• The finite temperature effects were accounted via the Langevin random field.
