Magnetic circular dichroism instrumentation at LNLS

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.
