We present the first measurements of the differential conductance of Co wires grown on top of Cu(110)-p(2 × 3)N (Cu 3 N). We apply scanning tunneling spectroscopy (STS) in constant height and constant current mode to access the electronic density of

In this study, three different types of multi-wall carbon nanotubes (MWCNTs) were compared as nanostructured reinforcements in epoxy polymers: commercially available CVD-MWCNTs, synthesised in an industrial process, aligned-CVD-MWCNTs and arc-grown M

We use spin-resolved scanning tunneling spectroscopy with a Cr-covered W-tip to investigate the magnetic switching of single Co islands on Cu ( 1 1 1 ) in polar magnetic fields. The observed hysteretic curve resembles a shape which is well known from

New insights into nanomagnetism: spin-polarized scanning tunneling microscopy and spectroscopy studies

Autor: Guillemin Rodary, Sebastian Wedekind, Hirofumi Oka, Dirk Sander, Jürgen Kirschner, Valeri S. Stepanyuk, P. A. Ignatiev, L. Niebergall

Publikováno v: SPIE Proceedings.

We perform low-temperature spin-polarized scanning tunneling microscopy (SP-STM) and spectroscopy measurements in magnetic fields to gain new insights into nanomagnetism. We use the magnetic field to change and control magnetizations of a sample and
