Correlation between Faraday rotation and bismuth and lead contents in LPE YIG films

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Conclusions

The main results of the present paper can be summarized as follows:

  1. a)

    By choosing suitable PbO-B2O3-Bi2O4 melts combined with appropriategrowth conditions it is possible to reduce significantly the content of lead atoms in garnet films leading to the incorporation of approx. 0·1 Pb per one Bi atom (y/x≈ ≈ 0·1).

  2. b)

    Account of the interference of the respective YL γ2,3, BiM α1 and PbM α1, PbM β1 X-ray lines in the EPMA method enables sufficiently exact determinations of Bi and Pb contents in garnet films.

  3. c)

    Determination of Bi contents in thin garnet films (1–2 μm) is made possible by measuring the FR near 500 nm. The magnitude of the minumum of the specific Faraday coefficient determines the Bi content and it has been shown that this value is not influenced by the presence of Pb ions.
