(a) A schematic illustration of the BiY2Fe5O12/Au-NP model used for the numerical calculation based on a finite-difference time-domain method. Plane electromagnetic waves with the polarization along the x direction and the wave vector k along the z direction are applied to the BiY2Fe5O12/Au-NP model. E denotes an electric field of the electromagnetic waves. (b,c) Simulated distributions of the electric field intensity |E| in the BiY2Fe5O12/Au-NP model in the x-y plane across the centre of the Au NP at λ=690 nm (b) and 500 nm (c).
