What Are the Challenges in Studying Exchange Anisotropy at the Nanoscale?
Despite its promising applications, studying exchange anisotropy at the nanoscale presents several challenges:
1. Interface Quality: The properties of the interface between the ferromagnetic and antiferromagnetic layers are critical. Any imperfections can significantly affect the exchange interaction. 2. Thermal Stability: Maintaining stable exchange anisotropy at varying temperatures is challenging, particularly for applications that require high thermal stability. 3. Material Selection: Identifying suitable material combinations that exhibit strong exchange coupling and desirable magnetic properties is a complex task.
