Abstract

We present small angle neutron scattering experiments on (001) Fe/Ir superlattices. A short period oscillated coupling is observed. However, antiferro and ferromagnetic peaks are simultaneously measured on neutron diagram, which cannot be simply explained. A biquadratic coupling model is proposed to account for this behaviour.
