title = "Manipulation of Faraday rotation in Bi-substituted yttrium-iron garnet film using electromagnetic interaction between Au nanoparticles in two-dimensional array",
abstract = "The Faraday rotation in Bi-substituted yttrium-iron garnet thin films, in which an artificially fabricated Au nanoparticle array is embedded, is studied as a function of lattice spacing compared with the extinction spectra. With decreasing lattice spacing in the Au array, the wavelengths corresponding to the enhanced Faraday rotation and the extinction peak showed blueshifts in the same manner. This indicates that Faraday rotation can be manipulated by means of the wavelength shift of localized surface plasmon resonance that originates from the change in electromagnetic interaction between Au nanoparticles.",

The present work was supported by a Grant-in-Aid for Scientific Research under Grant No. 19310077, from the Ministry of Education, Culture, Sports, Science, and Technology of Japan. FIG. 1. SEM images of the Bi:YIG film on Au NP array after heat treatment at 700 ° C . The heat treatment does not change the Au NP array structure. FIG. 2. XRD profiles of Bi:YIG film with Au NP array before and after heat treatment. The XRD profile after heat treatment indicates the well-crystalline Bi:YIG film that coexists with the Au NP array, although only the diffraction pattern of Au is observed before heat treatment. FIG. 3. (a) The extinction and Faraday rotation spectra of Bi:YIG films on Au NP arrays with different lattice spacings after heat treatment. The Faraday rotation of Bi:YIG film without Au NP is also shown. (b) The wavelengths corresponding to the enhanced Faraday rotation and the extinction peak of Bi:YIG films on Au NP arrays after heat treatment are plotted as a function of lattice spacing d . The inset shows the wavelength of peak extinction in bare Au NP arrays. ",
