... about half of that found in reference [11]. The H c is plotted as a function of x in Fig. 6. In general, H c increases in the x range from 15 A ˚ to 30 A ˚ (or 60 A ˚ ) and decreases in the x range ... thereafter. According to ref- erence [12], the H c behaviors are caused by the spin coupling and decoupling effects at the NiFe/IrMn interface as x increases. As discussed before,...
