|Abstract:||For the double exchange-biased IrMn/NiFe/FeMn structures, the pinning directions at IrMn/NiFe and NiFe/FeMn interfaces were set either parallel or antiparallel to each other by field annealing. Exchange bias and magnetotransport properties in IrMn/NiFe/FeMn trilayers were studied and compared with those of IrMn/NiFe and NiFe/FeMn bilayers. The dependence of exchange bias on the thickness of NiFe layer was different for parallel and antiparallel pinnings. A remarkable increase in resistance was observed which should be attributed to domain-wall resistance induced by the twisted spin structure. The spin configuration of twisted spin structure was simulated by one-dimensional atomic model. © 2008 The American Physical Society.|
