文摘
- •
Magnetic structure around the interface between IrMn and NiFe layers is proposed.
- •
XMCD is element-specific with high resolution to probe the magnetic moments.
- •
Mechanism relies on spin moments of Fe and Ni change differently with AFM thickness.
- •
Strong exchange coupling between Fe and AFM layer around the interface is found.
- •
Weaker exchange coupling between Ni and AFM layer around the interface is observed.
