Times Cited Count：422 Percentile：99.41(Materials Science, Multidisciplinary)We experimentally investigate and quantitatively analyze the spin Hall magnetoresistance (SMR) effect in ferromagnetic insulator (FI)/Pt and FI/nonmagnetic metal/Pt hybrid structures. For the FI, we use either YIG, nickel ferrite, or magnetite and for the nonmagnet, Cu or Au. The SMR is theoretically ascribed to the combined action of spin Hall and inverse spin Hall effect in the Pt top layer. It therefore should characteristically depend upon the orientation of the magnetization in the adjacent ferromagnet and prevail even if an additional, nonmagnetic metal layer is inserted between Pt and the ferromagnet. Our experimental data corroborate these theoretical conjectures. Using the SMR theory to analyze our data, we extract the spin Hall angle and the spin diffusion length in Pt. For a spin-mixing conductance of 
m
, we obtain a spin Hall angle of 0.11 
0.08 and a spin diffusion length of (1.5 0.5) nm for Pt in our samples.

Times Cited Count：34 Percentile：73.64(Physics, Fluids & Plasmas)Radial electric field in known to be one of the drivers for the parallel ion flow in the SOL. It contributes to the ion Pfirsch-Schluter flow and determines the return parallel flow compensating poloidal ExB drift. It was established recently that 2D fluid codes EDGE2D and SOLPS underestimate the predicted Er in the SOL compared to experimentally measured values. The present work demonstrates that this underestimate can be responsible for the large discrepancy between measured and simulated parallel ion flows in the SOL. Provided radial electric field was modelled correctly by the codes, an increase in the predicted Mach number of the parallel ion flow by up to a factor 3 for the JET could be expected. This would entirely eliminate the difference between the experimentally determined part of the ion flow that depends on the toroidal field direction, and the modelled ion flow attributed to drifts. Discrepancy between measured and simulated flows in ASDEX-Upgrade was also reduced.

During severe accident scenarios, actinides can volatilize and subsequently react with ferrous metal in different parts of the reactors. Their behavior and potential release to the environment needs to be investigated. To this end, this study investigates high temperature reactions of actinides with ferrous metals. A focused light was used as a heating device and the heated materials were analysed by SEM-EDS and XRD to acquire information about the formed phases and specific sorption phenomena on steel surface. This study provides fundamental information about the distribution and chemical properties of actinide compounds potentially formed in the damaged reactor vessel, as well as their vapor and aerosol behavior, for the planned decommissioning of the Fukushima NPPs.
