Antivortex domain walls observed in permalloy rings via magnetic force microscopy
Roy, P. E.; Lee, J. H.; Trypiniotis, Theodossis; Anderson, D.; Jones, G. A. C.; Tse, D.; Barnes, C. H. W. (2009)Magnetic domain walls in patterned permalloy ring elements of different widths and thicknesses have been probed by magnetic force microscopy and micromagnetic simulations. We report the experimental observation of antivortex ...

Localized magnetic fields in arbitrary directions using patterned nanomagnets
McNeil, R. P. G.; Schneble, R. J.; Kataoka, M.; Ford, C. J. B.; Kasama, T.; Dunin-Borkowski, R. E.; Feinberg, J. M.; Harrison, R. J.; Barnes, C. H. W.; Tse, D. H. Y.; Trypiniotis, Theodossis; Bland, J. A. C.; Anderson, D.; Jones, G. A. C.; Pepper, M. (2010)Control of the local magnetic fields desirable for spintronics and quantum information technology is not well developed. Existing methods produce either moderately small local fields or one field orientation. We present ...

Static and dynamic magnetic properties of Ni80 Fe20 square antidot arrays
Tse, D. H. Y.; Steinmuller, S. J.; Trypiniotis, Theodossis; Anderson, D.; Jones, G. A. C.; Bland, J. A. C.; Barnes, C. H. W. (2009)We have investigated both static and dynamic magnetic properties of square antidot arrays in a ferromagnetic thin-film structure of Au (2 nm)/ Ni80 Fe20 (27.6 nm) on a SiO2 500 nm/Si substrate using magneto-optic Kerr ...
