  • Large amplitude magnetization dynamics and the suppression of edge modes in a single nanomagnet 

    Keatley, Paul Steven; Gangmei, Prim; Dvornik, Mykola; Hicken, R.J.; Childress, J.R.; Katine, J.A. (American Institute of Physics, 2011)
    Large amplitude magnetization dynamics of a single square nanomagnet have been studied by time-resolved Kerr microscopy. Experimental spectra revealed that only a single mode was excited for all bias field values. Micromagnetic ...
  • Time- and vector-resolved Kerr microscopy of hard disk writers 

    Gangmei, Prim; Keatley, Paul Steven; Yu, W.; Hicken, R.J.; Gubbins, M.A.; Czoschke, P.J.; Lopusnik, R. (American Institute of Physics, 2011)
    Time-resolved scanning Kerr microscopy has been used to make wafer level measurements of magnetization dynamics within the yoke and pole piece of partially built hard disk writer structures. Three Cartesian components of ...
  • Ultrafast magnetization dynamics of spintronic nanostructures 

    Keatley, Paul Steven; Kruglyak, V.V.; Gangmei, Prim; Hicken, R.J. (Royal Society, 2011)
    The ultrafast (sub-nanosecond) magnetization dynamics of ferromagnetic thin films and elements that find application in spintronic devices is reviewed. The major advances in the understanding of magnetization dynamics in ...
