Theory of a magnetic microscope with nanometer resolution
Peter Johansson, S. Peter Apell, D. R. Penn
We propose a theory for a type of apertureless scanning near field microscopy that is intended to allow the measurement of magnetism on a nanometer length scale. A scanning probe,…

Circularly polarized light emission in scanning tunneling microscopy of magnetic systems
S. P. Apell, D. R. Penn, P. Johansson
Light is produced when a scanning tunneling microscope is used to probe a metal surface. Recent experiments on cobalt utilizing a tungsten tip found that the light is circularly po…
