The doping of charge carriers into the CuO 2 planes copper oxide Mott insulators causes a gradual destruction antiferromagnetism and emergence high-temperature superconductivity. Optimal superconductivity is achieved at concentration p beyond which further increases in cause weakening eventual disappearance A potential explanation for this demise that ferromagnetic fluctuations compete with overdoped regime. In case, phase very low temperatures predicted to exist disappears. Here we report...
It is shown that attempts to accurately deduce the magnetic penetration depth λ of overdoped BaFe(1.82)Co(0.18)As₂ single crystals by transverse-field muon spin rotation (TF μSR) are thwarted field-induced order and strong vortex-lattice disorder. We explain how substantial deviations from field distribution a nearly perfect vortex lattice one or both these factors also significant for other iron-arsenic superconductors, this introduces considerable uncertainty in values obtained TF μSR.
Abstract The determination of inorganic anions in uranium ore concentrates (UOCs) is useful to nuclear forensics for establishing the provenance sample materials. In this collaborative study, quantitation was carried out on three UOC reference materials from National Research Council Canada: UCLO-1 ( https://doi.org/10.4224/crm.2020.uclo-1 ), UCHI-1 https://doi.org/10.4224/crm.2020.uchi-1 and UPER-1 https://doi.org/10.4224/crm.2020.uper-1 ). analytes were extracted into water characterized...

In June 2020, observations of anthropogenic radionuclides in Estonia, Finland, and Sweden that were not related to any acknowledged environmental release led a comprehensive investigation on the source cause unusual emissions. Several observed list Comprehensive Nuclear-Test-Ban Treaty (CTBT) relevant as an indicator potential nuclear test, warranted detailed investigation. While analysis aerosol samples coupled with Atmospheric Transport Dispersion Modelling (ATDM) is standard approach for...
