TL;DR: In this paper, room temperature ferromagnetic ordering has been observed in a rutile TiO2 polycrystalline sample after 4 MeV Ar5+ ion irradiation.

TL;DR: In this article, recipes for the successful conditioning of tungsten and nickel moderators, for application in positron-scattering experiments, are reported. And the comparative performance of those moderators, as a result of these procedures, is assessed.

TL;DR: In this article, a comprehensive study employing Raman spectroscopy is reported on N and Li implantation effects in ZnO, showing that the deep acceptor level may be at approximately 300 ǫmeV above the valence band consistent with previous results.

TL;DR: In this article, the first measurements of total cross sections for positron scattering from the important bio-molecule 3-hydroxy-tetrahydrofuran were reported.

TL;DR: In this paper, the authors revisited positron scattering from molecular hydrogen, in an attempt to provide accurate total cross-section data against which theoretical calculations might be benchmarked, and the present data were measured over the energy range 0.1 -50 eV and, where possible, are compared to results from previous experiments and calculations.
