Time- and vector-resolved magneto-optical Kerr effect measurements of large angle precessional reorientation in a 2*2 [micro][m.sup.2] ferromagnet

The precessional dynamics of a 2*2 [micro][m.sup.2] CoFe/NiFe element stimulated by an in-plane pulse magnetic field are examined by using time- and vector-resolved Kerr microscopy measurements and micromagnetic simulations. The simulations have shown that only the magnetization of the center region has undergone large angle reorientation, while the canted magnetization at the edges of the element has remained pinned.
