Exchange between deep donors in semiconductors: a quantum defect approach
W. Wu, A. J. Fisher
Exchange interactions among defects in semiconductors are commonly treated within effective-mass theory using a scaled hydrogenic wave-function. However such a wave-function is onl…

Determining surface magnetization and local magnetic moments with atomic scale resolution
W. A. Hofer, A. J. Fisher
We propose a method to determine the direction of surface magnetization and local magnetic moments on the atomic scale. The method comprises high resolution scanning tunneling micr…

Tip effects in scanning tunnelling microscopy of atomic-scale magnetic structures
W. A. Hofer, A. J. Fisher
The spin-polarized scanning tunnelling microscope (STM) can in principle resolve not only the electronic, but also the magnetic surface structure. We model recent STM measurements…
