We report on an electrical detection of current driven domain wall (DW) deformation induced by a current pulse injection in arc-shaped permalloy (Py) submicron wires. Current polarity and pulse length dependence were investigated under an assisting external magnetic field. Initial DW states prepared by an application of a large magnetic field were distributed to two distinct DW states. A current pulse application promoted transition between them. In addition, the third DW state was established only by an application of the short pulses (< 50 ns). This result suggests the possibility of the high-speed control of the DW dynamics.
