The M_4,5spectrum of⁵⁸Ce and the γ-α phase transition

Evidence for Coexistence of Bulk Superconductivity and Itinerant Antiferromagnetism in the Heavy Fermion System CeCo(In1−xCdx)5

“…The variation of valence between the two phases is less than 0.03. We cannot exclude the formation of an oxide layer on the metallic cerium during the few minutes needed to transfer the sample into the chamber, but the value of v f is in good agreement with the 57% of Ce 3+ found previously in the α phase on an in-situ evaporated cerium film40. The absence of valence variation is in agreement with Compton scattering experiments31.…”

Influence of thermoelastic stresses on self-focusing of quasicontinuous radiation

“…Because of the appearance of the peaks C and E in the 3d XAS spectrum of C e 0 2 , our results do not confirm the previous data reported by Ottewell et al (1973) and Bonnelle et af (1974). The data of the former authors show no sign of either C o r E, and their spectrum closely resembles that of La3+ with which Ce4+ is iso-electronic.…”

Changes in the electronic structure of cerium due to variations in close packing

“…Therefore, acquiring single-phase samples of metals at or near this transition, such as manganese ͑four phases͒, cerium ͑four phases͒, and plutonium ͑six phases͒, is uncertain, rendering spectroscopic techniques with low spatial resolution questionable. 4 Producing large single crystals of these metals is even more difficult, and for many of them has yet to be accomplished. Rather than struggling to generate single-phase or singlecrystal samples of these complex metals, one may take the route of using an experimental technique that probes small portions of a sample, circumventing crystal growth problems.…”
