Recently, current-induced magnetization switching CIMS behavior in current-perpendicular-to-plane CPP exchange-biased spin valve ESPV nanopillars has been attracting great attention. In this paper, we experimentally study the CIMS in a special antisymmetric ESPV structure. With the increase of the external magnetic field, the device shows a transition from inverted CIMS to normal CIMS, which is possibly due to the different magnetic configuration in the antisymmetric ESPV.
