TL;DR
This paper reports on magnetically dependent plasmon drag effects in permalloy structures, showing enhanced photovoltages at plasmon resonance and magnetic hysteresis, suggesting mechanisms beyond simple heating.
Contribution
It introduces the observation of magnetically dependent plasmon drag in permalloy structures and discusses potential mechanisms beyond heating effects.
Findings
Photovoltages are enhanced at plasmon resonance.
Photovoltages depend on magnetic field with hysteresis.
Heating alone cannot explain the observed effects.
Abstract
Significant photovoltages are observed in permalloy grating-like structures in response to pulsed laser light illumination. Electric signals are enhanced at plasmon resonance conditions and show a clear dependence on the magnetic field with a characteristic hysteresis. Estimations show that the effect could not be explained solely by the laser-induced heating. Alternative mechanisms are discussed.
