Qualitative and quantitative differences in the absorption spectra of electron-irradiated reflective coatings based on mixtures of BaTio3 powder with ZrO2 micro- or nanopowder of different concentrations

The effect of the concentration and size (micro- or nanoparticles) of zirconium dioxide powders, heated in mixtures with barium titanate powder, on the radiation resistance of reflecting coatings on their basis is analyzed during accelerated electron irradiation. It is shown that nanoparticles provide increased radiation resistance of the coatings compared to microparticles.     

The suppression of magnetic level coincidences in tilted magnetic fields in the HgTe quantum well as a consequence of electronic phase transitions under quantum hall effect conditions

Spin level coincidences in the HgTe quantum well observed in comparatively weak tilted magnetic fields were found to transform into anticrossings, and gaps formed in anticrossings nonmonotonically depended on the level filling factor. This behavior was indicative of phase transitions into a quantum Hall ferromagnet state.

Features of the surface morphology of brass and bronze upon irradiation with a high power ion beam

The change in the morphology and surface composition of copper alloys (brass LS 59-1, bronzes BrOS 10-10 and BrAJ 9-4) upon irradiation with a high power ion beam of nanosecond duration is studied. It is shown that craters are mainly formed at the location of lead or sulfur inclusions. The reverse deposition of zinc onto the surface of brass is found. Possible mechanisms of these phenomena are considered.
