Physique

The nature of domain walls in ultrathin ferromagnets revealed by scanning nanomagnetometry

The capacity to propagate magnetic domain walls with spin-polarized currents underpins several schemes for information storage and processing using spintronic devices. A key question involves the internal structure of the domain walls, which governs…

Four-coordinate nickel(II) and copper(II) complex based ONO tridentate Schiff base ligands: synthesis, molecular structure, electrochemical, linear and nonlinear properties, and computational study

We report the synthesis, characterization, crystal structures, nonlinear-optical (NLO) properties, and density functional theory (DFT) calculations of nickel(II) and copper(II) complex based ONO tridentate Schiff base ligands: two mononuclear…

Intensity- and phase-noise correlations in a dual-frequency vertical-external-cavity surface-emitting laser operating at telecom wavelength

The amplitude and phase noises of a dual-frequency vertical-external-cavity surface-emitting laser (DF-VECSEL) operating at telecom wavelength are theoretically and experimentally investigated in detail. In particular, the spectral behavior of the…

Intraband and intersubband many-body effects in the nonlinear optical response of single-wall carbon nanotubes

We report on the nonlinear optical response of a mono-chiral sample of (6,5) single-wall carbon nanotubes by means of broad-band two-color pump-probe spectroscopy with selective excitation of the S11 excitons. By using a moment analysis of the…

Plasmon-Assisted Production of Reactive Oxygen Species by Single Gold Nanorods

The generation of reactive oxygen species by gold nanorods under ultrashort-pulsed irradiation is investigated at the single-nanoparticle level. Near-infrared femtosecond pulses induce the production of hydroxyl radicals in a hydrogel medium through…
