Engineers design nanostructured diamond metalens for compact quantum technologies

ScienceDaily.com: Nanotechnology News - Tue, 06/11/2019 - 22:51
By finding a certain kind of defect inside a block of diamond and fashioning a pattern of nanoscale pillars on the surface above it, engineering researchers can now control the shape of individual photons emitted by the defect. Because those photons carry information about the spin state of an electron, such a system could be used as the basis for compact quantum technologies.

'Sandwich' structure key to thin LSMO films retaining magnetic properties

NanoWerk.com - Tue, 06/11/2019 - 22:16
The oxide ceramic material lanthanum strontium manganite (LSMO) retains its magnetic properties in atomically thin layers if it is 'sandwiched' between two layers of a different ceramic oxide, lanthanum strontium chromium oxide. The findings have implications for future use of LSMO in spintronic-based computing and storage devices.
