(a) SEM image showing drop-evaporated AuNR distribution on film surface. Top inset: drop-evaporated spot. Red dot indicates the approximate position where the SEM image was recorded. Scale bar = 1 mm. Bottom inset: bright-field image taken at the edge of the drop-evaporated spot under 20× objective, showing details of the highly non-uniform AuNR aggregation. Scale bar = 50 μm. (b) Pump-probe setup for measuring transient magnetization. Abbreviations: BS: beam splitter, BSP: polarizing beam-splitter, CH: chopper, H: external field, L: lens, M: mirror, ODL: optical delay line, OBJ: objective, P: polarizer, QPD: quadrant photodiode, S: sample, VF: variable filter.
