We investigated the bubble-domain dynamics in TbFeCo wires with perpendicular magnetization under electric current flows. In TbFeCo wires with relatively low saturation magnetization (M-s), the current pulse caused the bubble domains to collapse without moving. In TbFeCo wires with relatively high M-s, however, the bubble domains grew in the current direction. We explain these shape changes by assessing the M-s-dependent forces caused by the exchange field and magnetostatic field. We also found that we could control the current-induced behaviors of the bubble domains by using an external magnetic field. (C) 2015 The Japan Society of Applied Physics
