Kerr-microscopy of magnetic nanostructures — •Christian Dicken1,2, Klas Lindfors1,2, Mario Hentschel1,2, and Markus Lippitz1,21Max-Planck-Institute for Solid State Research, Stuttgart — 24th Physics Institute, University of Stuttgart

Merging the fields of micromagnetism and plasmonics promises many new applications in both industry and science. As a first step towards experiments on micromagnetic particles, we use a combination of Sagnac interferometry and an improved sample design to measure the magnetization of isolated nickel-gold particle systems. With the present technique, we were able to observe the Kerr rotation of particles smaller than 90nm in diameter with an SNR of 28. We will show a model that describes the size dependence of the signal and allows us to adapt our sample design for even better performance.
