| Abstract | The optical absorption spectra in the region of the 4f(7) --> 4f(6)5d (t(2g)) transition energies of epitaxial layers of EuTe and Pb0.1Eu0.9Te, grown by molecular beam epitaxy, were studied using circularly polarized light, in the Faraday configuration. Under sigma(+) polarization a sharp symmetric absorption line (full width at half-maximum 0.041 eV) emerges on the low energy side of the band-edge absorption, for magnetic field intensities greater than 6 T. The absorption line shows a huge red shift (35 meV T-1) with increasing magnetic field. The peak position of the absorption line as a function of magnetic field is dominated by the d-f exchange interaction of the excited electron and the Eu2+ spins in the lattice. The d-f exchange interaction energy was estimated to be J(df)S = 0.15 +/- 0.01 eV. In Pb0.1Eu0.9Te the same absorption lime is detected, but it is broader, due to alloy disorder, indicating that the excitation is localized within a finite radius. From a comparison of the absorption spectra in EuTe and Pb0.1Eu0.9Te the characteristic radius of the excitation is estimated to be similar to10 Angstrom. |
