文摘

The magnetic properties of NiFe/CoO/α-Fe2O3 and NiFe/CoO are compared. Trilayer has lower irreversibility temperature than NiFe/CoO bilayer. At 180 K, trilayer has smaller exchange bias than bilayer due to AF/AF coupling. The magnetic properties of FM/AF layers can be tailored by a third AF layer.
