Canadian Mineralogist, 46(5), 1317-1322. https://doi.org/10.3749/canmin.46.5.1317Using X-ray absorption spectroscopy (XAS) at the Cu L2,3 and Co L2,3 edges, we demonstrate that the valence state of copper in the thiospinel carrollite (CuCo2S4) is Cu+ with a d count of Cu d9.8. The Co has a d count of d6.4, so that the highly cova... Read More about THE OXIDATION STATE OF COPPER AND COBALT IN CARROLLITE, CuCo2S4.
Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials (2008)
Journal Article

Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials. Physical review B: Condensed matter and materials physics, 78(10), https://doi.org/10.1103/physrevb.78.104403We show that Fe nanoislands capped with Al, Pd, and Pt protecting layers include an alloy at the interface with the capping layer, which explains the previously known capping layer dependence on the interparticle magnetic coupling. Vibrating sample m... Read More about Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials.
