Thin-film high-entropy alloy (HEA) superconductors have recently attracted a lot of attention, but their critical current density and potential usefulness in engineering applications has remained unclear. Here, the authors fabricate HEA films with re

Abstract We investigate the magnetic properties in carbonyl iron (CI) particles before and after Ni $$^{+}$$ + and H $$^{+}$$ + ion beam irradiation. Upon increasing temperatures, the saturation magnetization ( $$M_{\text {s}}$$ M s ) in hysteresis l

Abstract Several techniques have been proposed for kerfless wafering of thin Si wafers, which is one of the most essential techniques for reducing Si material loss in conventional wafering methods to lower cell cost. Proton induced exfoliation is one

We have developed a real-time dose monitoring system for a low-energy ion-beam facility. Before we developed the monitoring system, the system had given a substantial error of ±23% when we irradiated an ion beam with a dose as much as 3.0 × 1016 cm

We investigate the magnetic properties in a frustrated spin system of carbonyl iron (CI) particles before and after Ni+ ion beam irradiation. Upon increasing temperatures, the saturation magnetization exhibits an anomalous increase, which is more int

Si ions 2.3 MeV are implanted into nanodiamonds (NDs) at doses of 1×1012 ~ 1×1015 ions/cm2. The ion implantation not only creates silicon-vacancy (SiV) color centers but also reduces the size of the NDs from 50 nm to ~ 10 nm. As the Si dose is incr

A thin (2 μm) and relatively large area (3 × 3 mm2) diamond membrane was fabricated by cleaving a surface from a single crystal chemical vapor deposition (CVD) diamond wafer (3 × 3 mm2× 300 μm) using a hot implantation and ion-cut method. First,
