Abstract :
We report the first observation of magnetization reversal in (CoNi/Pt)6 small elements connected to a large area through submicron wide channels. Squares of size ranging from 0.2 μm×0.2 μm to 10 μm×10 μm and wire channels of linewidth ranging from 0.05 μm to 0.5 μm were fabricated by electron beam lithography and ion beam etching, and then studied by magneto-optical Kerr microscopy. Switching fields for magnetization and the reversal behavior of these dot elements were found to depend on the channel width, thereby providing a way of studying domain wall propagation in the wire channels
