We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin films ${\mathrm{Co}}_{0.975}{\mathrm{Ge}}_{0.025}{\mathrm{Cr}}_{2}{\mathrm{O}}_{4}$ (Ge-CCO) and ${\mathrm{CoCr}}_{2}{\mathrm{O}}_{4}$ (CCO) under low high fields from 0.2 to 6.5 T. A characterization Ge-CCO at field was performed, results were compared with those pure CCO. The ferrimagnetic...

Abstract Stellite-6 (Co-based) and NiAl coatings (Ni-based) were deposited via HVOF spraying onto 304 stainless steels tested in a 20 kWth biomass fired bubbling fluidised bed (BFB) combustor for 20 h an industrial scale anthracite CFB boiler 1630 h. showed excellent corrosion resistance both combustion systems because of the formation outermost Cr2O3 layer spinel CoCr2O4 beneath, whereas coati...

Nano-sized spinel cobalt chromite oxide CoCr2O4 and its substituted forms CoCr2−xAlxO4 (0 ≤ x 2) have been successfully synthesised by wet chemical route. The prepared powders were characterised means of thermal analysis (DTA/TGA), X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Brunauer–Emmett–Teller (BET), UV–visible techniques (UV–Vis) colorimetric analyses (L*...
