Permalloy grating-like structures exhibit significant photovoltages in response to pulsed laser light illumination, with enhanced electrical signals at plasmon resonance conditions. The dependence of the signals on the magnetic field with characteristic hysteresis suggests alternative mechanisms beyond laser-induced heating.
Significant photovoltages are observed in permalloy grating-like structures in response to pulsed laser light illumination. Electrical 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 laser-induced heating. Alternative mechanisms are discussed. (C) 2021 Optical Society of America
