Abstract

Quartz, glass plate samples dispersed with YIG ultrafine particles about 30 nm in mean dimension were prepared through synthesis by the alkoxide method. Using these samples, the light absorption spectra of the YIG ultrafine particles were measured from the wavelength λ=450 nm up to 1800 nm. The peak of the spectra of the YIG ultrafine particles around λ=600 nm is shifted to a lower wavelength, while the peak around λ=900 nm is shifted to a higher wavelength compared with those of bulk YIG. In addition, the latter peak broadens
