The 3D Inverse Faraday effect in a magnetophotonic microcavity. (a) Scheme of the experiment. The sample is a magnetophotonic microcavity formed by the magnetic film (brown) sandwiched in between two nonmagnetic Bragg mirrors formed by several pairs of the dielectric layers N1 and N2 (gray). The circularly polarized pump excites the magnetic film and the linearly polarized probe is used to observe the magnetization dynamics at some time delay. (b) SEM image of the MPMC sample cross-section. (a,c) Calculated distributions of the optically generated effective magnetic field inside the magnetic layer of the MPMC (a) and inside a single magnetic film (c) are shown on the front side of the samples by green color demonstrating the 3D and 2D localization of the IFE, respectively.
