Abstract

Fine tuning of exchange coupling constants was demonstrated in synthetic antiferromagnetic multilayers consisting of three ferromagnetic layers and two spacer layers. The effects of interfacial roughness on both the bilinear and biquadratic exchange coupling constants were studied. A model was developed to simulate the behavior of such synthetic antiferromagnetic multilayer system. Detailed exchange coupling constants, both bilinear and biquadratic, were extracted from experimental data by using the model and compared for different samples.
