The influence on the structural and optical properties of Co or Mn alloying
in beta -FeSi2 has been investigated by X-ray diffraction (XRD), conversio
n electron Mossbauer spectroscopy (CEMS), mu -Raman spectroscopy, and trans
mittance measurements. Fe1-xMxSi2 thin films (M = Co, Mn; 0 < x < 0.20) wer
e produced by co-deposition at room temperature of Fe and Co or Mn onto Si(
001) substrates using the pulsed laser deposition (PLD) technique and in-si
tu annealing at 700 degreesC. (C) 2001 Elsevier Science B.V. All rights res
