Measuring magnetization in antiferromagnetic materials with two sublattices can be effectively achieved using techniques such as neutron scattering, NMR, and muon spin rotation. Neutron scattering allows for the measurement of the magnetic structure factor, S(q), which helps in proposing a magnetic structure that corresponds to the observed data. NMR is also a viable method for investigating sublattice magnetization. The discussion suggests that a SQUID device could be integrated directly onto the material for measurement purposes. These methods provide valuable insights into the magnetic properties of antiferromagnetic materials.
