文摘The bias field dependence of the rotation direction of the dumbbells,contracted from multi-branched domains,was experimentally studied.Moreover,it was found that the rotation direction of these dumbbells can be reversed by increasing the amplitude of the testing bias pulses with quite narrow width.
