Title: "Atom Trap, Krypton-81, and Saharan Water"
Abstract: Since radiocarbon dating was first demonstrated in 1949, the field of trace analyses of long-lived cosmogenic isotopes has seen steady growth in both analytical methods and applicable isotopes. The impact of such analyses has reached a wide range of scientific and technological areas. A new method, named Atom Trap Trace Analysis (ATTA), was developed by our group and used to analyze 81Kr (t1/2 = 2.3?105 years, isotopic abundance ~ 1?10-12) in environmental samples. In this method, individual 81Kr atoms are selectively captured and detected with a laser-based atom trap. 81Kr is produced by cosmic rays in the upper atmosphere. It is the ideal tracer for dating ice and groundwater in the age range of 104–106 years. As the first real-world application of ATTA, we have determined the mean residence time of the old groundwater in the Nubian Aquifer located underneath the Sahara Desert. Moreover, this method of capturing and probing atoms of rare isotopes is also applied to experiments that study exotic nuclear structure and test fundamental symmetries.

Title:"EPITAXY, MAGNETISM AND MAGNETOTRANSPORT OF Fe-MgO (001) HETEROSTRUCTURES"
Abstract: The aim of this talk is to give an overview of the results
obtained during the last few years at the IMM concerning the epitaxy, magnetic
and magnetotransport properties of different types of epitaxial Fe-MgO
(001) nanostructures. With this purpose, we have first performed an extensive
study on the epitaxy of Fe on MgO(001), as well as that of MgO on Fe(001).
This has allowed us to fabricate ultrathin Fe(001) films, Fe/MgO/Fe trilayers
and Fe/MgO superlattices on MgO, Si and GaAs (001) substrates with control
of the structure and morphology at the atomic and nanometric level, extended
to the micrometric level by the use of lithography techniques. Once
the influence of the different deposition parameters on the structure and
morphology was understood and controlled, we embarked on a complete study
on the different magnetic and magnetrotransport properties of these nanostructures.
