“…The diffraction peak from CeO 2 (111) contributes to the broadening of the YIG (400) peak. Furthermore, the precipitation of CeO 2 increases the volume fraction of YIG in Ce:YIG; since YIG has a smaller lattice parameter than Ce:YIG due to the larger ionic radius of Ce 3+ (0.118 nm) than Y 3+ (0.106 nm), 31 the angle of diffraction from the crystallized YIG/Ce:YIG sample should increase with the volume fraction of YIG.…”

For the realization of integrated nonreciprocal photonic devices for optical communication, on-chip monolithic integration of magneto-optical materials onto silicon remains a challenge. Implemented with pulsed laser deposition (PLD), a MgO interfacial layer is introduced to overcome the material incompatibilities between a silicon substrate and magneto-optical thin films of yttrium iron garnet (YIG). With a thickness of ∼40 nm, the amorphous interfacial layer of MgO can effectively inhibit interdiffusion across YIG/Si and promote the growth of a high-density, high-phase-purity polycrystalline garnet structure in the bilayer of YIG/Ce:YIG. Such modified chemistry and microstructure in YIG/Ce:YIG lead to enhanced magneto-optical properties, including an ∼38% increase in Faraday rotation and an ∼15% increase in saturation magnetization, as well as an ∼20% increase in infrared (IR) transmission. Offering dual functions of diffusion barrier and structure template, the MgO layer demonstrated herein suggests a new remedy solution to heterogeneous interfaces in advanced thin film devices.
