Quantification of magnetic domain disorder and correlations in antiferromagnetically coupled multilayers by neutron reflectometry

摘要: The in-plane correlation lengths and angular dispersion of magnetic domains in a transition metal multilayer have been studied using off-specular neutron reflectometry techniques. A theoretical framework considering both structural disorder has developed, quantitatively connecting the observed scattering to length local magnetization vector about mean macroscopic direction. antiferromagnetic domain structure is highly vertically correlated throughout multilayer. We are easily able relate determined magnetoresistance experiments.
