Abstract Polarized neutron reflectometry (PNR) has played an essential role for the exploration of nanomagnetic and spintronic materials, including exchange coupled magnetic superlattices, exchange bias systems between ferromagnetic and antiferromagnetic films, spin valves, exchange springs between soft and hard magnetic films, superconducting proximity effects, periodic lateral magnetic patterns, and magnetic nanoparticles. The main virtues of PNR are depth-resolved vector magnetometry in the film plane, high sensitivity to magnetic interfaces, and statistical analysis of magnetic domain fluctuations. Recently the capabilities of PNR have been carried over from steady state to dynamic investigations of magnetization reversal processes. This review outlines the basic theory of PNR, including specular reflectivity and off-specular scattering treated in the distorted-wave Born approximation. The theory is exemplified by model calculations and by discussions of pertinent PNR work.
