Abstract

Magnetically soft/hard exchange-coupled layered structures with modulated exchange coupling were deposited by sputtering on Si (100) substrates. The interfacial exchange coupling strength between the soft and hard layers was tailored by inserting a thin nonmagnetic insulating Si₃N₄ layer. Results showed that the reduction in the exchange coupling reduces the nucleation field of the soft layer and increases the irreversible switching field of the hard layer.
