- We demonstrate that switching of ferroelectric thin-films sandwiched between metallic electrodes can be controlled by laser-assisted heating, reminiscent of heat-assisted magnetic recording. We employ electrical switching cycles that quantify the electrically switchable remanent polarization $P_\mathrm{r}$ and show that 300\,ns voltage pulses alone change the polarization by less than $ΔP<P_\mathrm{r}$. Transient heating of the metallic top electrode by synchronized ns laser-pulses induces a reversal $ΔP^\mathrm{L}>P_\mathrm{r}$ of the average polarization. The transient average temperature modeled by the heat equation can rationalize the polarization change observed for different relative timing $Δt$ of the laser pulse, if it arrives before the electrical pulse.
