Abstract
We experimentally demonstrated the increase of in-plane magnetic anisotropy in Au/Co/Au nanostructures by localized surface plasmon resonance (LSPR). When an array of Au/Co/Au square patch nanostructures was illuminated with linearly polarized light whose wavelength was 750 nm, the localized surface plasmons were resonantly excited in the nanostructures. From the measurement results of polar magneto-optical Kerr effect curves, we observed the magnetic anisotropy field increase in the Au/Co/Au nanostructure due to the excited surface plasmons. The in-plane magnetic anisotropy energy density was increased about 24%.
Highlights
Magnetic properties of magnetic devices strongly depend on their materials, the fabrication process, and the surrounding environments
Our group has reported that the longitudinal magneto-optical Kerr effect and magneto-optical figure of merit in Au/Co/Au nanostructure is enhanced by the localized surface plasmons excitation[21]
Magnetic anisotropy is an essential factor for practical applications, because it determines the thermal stability of magnetic devices, like magnetic random access memory (MRAM) and magnetic recording devices, just to name a few[22,23]
Summary
Magnetic properties of magnetic devices strongly depend on their materials, the fabrication process, and the surrounding environments. Reflection www.nature.com/scientificreports on some of these results made clear that Hk was drastically increased when the surface plasmons were excited in the structure (λ = 750 nm).
