(a) Cross-sectional electric field |E| profile for 10 nm × 40 nm AuNR on 15 nm permalloy with 1 nm spacer layer at plasmon resonance, calculated using Lumerical Solutions. Simulation mesh size = 0.5 nm in the vicinity of the AuNR. Dotted lines represent the boundaries of the permalloy (Py) film. (b) Temperature-dependence of magnetization for permalloy, calculated using M(T) ~ (1 − T/TC)β.
