  • Imaging the equilibrium state and magnetization dynamics of partially built hard disk write heads 

    Valkass, Robert A.J.; Yu, Wei; Shelford, L.R.; Keatley, Paul Steven; Loughran, T.H.J.; Hicken, R.J.; Cavill, Stuart A.; van der Laan, Gerrit; Dhesi, Sarnjeet S.; Bashir, Muhammad A.; Gubbins, M.A.; Czoschke, P.J.; Lopusnik, R. (American Institute of Physics (AIP), 2015-06-08)
    Four different designs of partially built hard disk write heads with a yoke comprising four repeats of NiFe (1 nm)/CoFe (50 nm) were studied by both x-ray photoemission electron microscopy (XPEEM) and time-resolved scanning ...
  • 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 ...
