WebNov 28, 2014 · In [Pt/Co] multilayers (ML) exchange coupled to IrMn, the magnitudes of the exchange bias field H{sub E} and coercivity H{sub C} measured along the perpendicular to film direction, can be tailored by (i) varying the thickness of the Co layers (t{sub Co}) inside the ML and/or (ii) inserting a Pt spacer between the ML and the antiferromagnetic ... WebNov 25, 2008 · Figure 4 shows H ex plotted as a function of the IrMn thickness (x) for the NiFe(50 Å)/IrMn(x) system under various conditions.As x ≤ 15 Å, there is almost no exchange-bias interaction, since J k > K AF x, where K AF is the anisotropy energy of IrMn [].When x increases from 15 Å to 60 Å, the IrMn pinning action becomes more effective, …
