Abstract: | Refractive-index and optical-absorption spectra of Bi-substituted yttrium iron garnet films, epitaxially grown by liquid-phase epitaxy, have been measured in the spectral regime 0.26 m![lE](/content/v4852261623233rj/xxlarge8806.gif) ![lambda](/content/v4852261623233rj/xxlarge955.gif) 1.9 m by thin-film interference for 0.52 m and by ellipsometry for![lambda](/content/v4852261623233rj/xxlarge955.gif) 0.52 m.

O12 films contain bismuth in the range O x 1.42, lead in the range 0.01 y 0.08 and platinum in the range 0.005<=z 0.03. There is satisfactory coincidence between the results from ellipsometry and thin-film interference in the overlapping wavelength region. The materials investigated are the same as reported earlier from this laboratory in ter mof their magnetic and magnetooptic properties. |
