Abstract
Heterostructured multilayer films of two different nanocrystals have been successfully fabricated by layer-by-layer stacking of Ti0.8Co0.2O2 nanosheet and Fe3O4 nanoparticle films. UV–Vis spectroscopy and AFM observation confirmed the successful alternating deposition in the multilayer buildup process. The average thickness of both Ti0.8Co0.2O2 nanosheet and Fe3O4 nanoparticle layers was determined to be about 1.4–1.7 and 5 nm, which was in good agreement with TEM results. Magneto-optical Kerr effect measurements demonstrated that the heteroassemblies exhibit gigantic magnetic circular dichroism (MCD) (2 × 104 deg/cm) at 320–360 nm, deriving from strong interlayer [Co2+]t2g–[Fe3+]eg d–d charge transfer which was further confirmed by X-ray photoelectron spectroscopy. Their structure-dependent MCD showed high potential in rational design and construction of high-efficiency magneto-optical devices.
