FONSECA, P. T. et al. Magnetic circular dichroism instrumentation at LNLS. Braz. J. Phys. [online]. 2007, vol.37, n.3b, pp.1171-1176. ISSN 0103-9733.

We describe the high-field (1.0 T) ultra high vacuum (1.6 10 - 9 mbar) controllable temperature (8 ºK up to > 350ºK) MCD setup designed and built at LNLS. We show, for nanocrystals of Hematite a-Fe2O3, illustrative results obtained at room and at low temperature.

Keywords : MCD; Dichroism; Hematite; Nanocrystal; Spectroscopy; Synchrotron light.
