TL;DR: In this article, the internal structure of magnetic domain walls in ultrathin Fe nanowires prepared on W(110) was studied using spin-polarized scanning tunneling microscopy.
Abstract: Spin-polarized scanning tunneling microscopy is employed to study the internal structure of $360\ifmmode^\circ\else\textdegree\fi{}$ magnetic domain walls in ultrathin Fe nanowires prepared on W(110). They are formed by pairs of winding $180\ifmmode^\circ\else\textdegree\fi{}$ walls in an increasing external magnetic field. Their width is governed by an equilibrium of exchange and Zeeman energy. In the relevant field range $(Bg~50\mathrm{mT})$ the demagnetizing energy contributes only indirectly via an increased wall width, i.e., a reduced effective anisotropy, and nonlocal effects are negligible.

TL;DR: In this paper, the electronic structure derived from the tunnelling spectra revealed peak in electron local density of states very close to the Fermi level, which was interpreted in terms of localised edge state caused by the topology of the π electrons networks typical for the zig-zag edges.

TL;DR: The observed two standing waves caused by separate spin and charge bosonic excitations are found to constitute direct evidence for a Luttinger liquid.
Abstract: Electronic standing waves with two different wavelengths were directly mapped near one end of a single-wall carbon nanotube as a function of the tip position and the sample bias voltage with high-resolution position-resolved scanning tunneling spectroscopy. The observed two standing waves caused by separate spin and charge bosonic excitations are found to constitute direct evidence for a Luttinger liquid. The increased group velocity of the charge excitation, the power-law decay of their amplitudes away from the scattering boundary, and the suppression of the density of states near the Fermi level were also directly observed or calculated from the two different standing waves.
