We report an extraordinary oxidation state of iron in the Fe-doped Bi 12 SiO 20 single
crystal. Magnetoelectric effect and changes of this effect under illumination of the sample …

Optical investigations of Cr-doped Bi 12 TiO 20 were performed at T= 300, 77 and 4.2 K. An
absorption line at λ= 456 nm at T= 4.2 K was detected. Line corresponds to E 5→ T 2 5 …

Abstract Pure and Fe-doped Bi 12 SiO 20 monocrystals have been studied. Five different
Feoncentrations (0.36, 1.8, 3.6, 7.2 and 10.8 mol%) were incorporated. An increase of the …

The correlation between photochromic effect and the effect of inducing the photoconductivity
in undoped and Al-, Ga-, Sn-, Cr-, Mn-, V-, Fe-, Cu-, Ag-, Mo-doped Bi 12 SiO 20 single …

The optical absorption spectra, photo-and electrochromic effects in Fe and Cu doped Bi 12
SiO 20 single crystals have been investigated in the range from 4000 to 28000 cm-1 at 80 …

The study of the magneto-optical properties of materials is very important for their
applications in practice. In this work, we are presented the connection between the …

The optical absorption spectra and photochromic effect of Bi12SiO20 pure and doped with
Cr and Mn single crystals have been investigated in the wave-length range between 8000 …

Using optical absorption and λ-modulated differential spectroscopy we investigated non-
doped and Fe-doped Bi 12 SiO 20 sillenite-type crystals. The obtained results show that the …

We report the observation of incident intensity and applied-field-induced increases in the
absorption coefficient of Bi_12SiO_20 at 514.5 nm. Absorption changes as large as 50 …
