TL;DR: In this article, light-controlled conductance switching of diarylethenes attached to Au(111) is reported, and reversible switching in self-assembled monolayers is established by means of optical spectroscopy.
Abstract: Light-controlled conductance switching of diarylethenes attached to Au(111) is reported (see figure). First, scanning tunneling microscopy is used to demonstrate reversible photoswitching for individual molecules. Second, reversible switching in self-assembled monolayers is established by means of optical spectroscopy.

TL;DR: Photochromic studies of diarylethenes with their switching unit linked to the surface of gold nanoparticles via a conjugated aromatic spacer show linker-dependent switching behavior.

TL;DR: It is shown that, under these ferromagnetic resonance conditions, a dc voltage is generated at a normal-metal electric contact to a ferromagnet with spin-flip scattering, which allows sensing of time-dependent magnetizations by established dc electronic techniques.
Abstract: A ferromagnet can resonantly absorb rf radiation to sustain a steady precession of the magnetization around an internal or applied magnetic field. We show that, under these ferromagnetic resonance conditions, a dc voltage is generated at a normal-metal electric contact to a ferromagnet with spin-flip scattering. The spin dynamics in the nonmagnetic region is accounted for by a frequency-dependent renormalization of the interface conductances. This mechanism allows sensing of time-dependent magnetizations by established dc electronic techniques.
