How we measure magnetisation in antiferromagnetics?

[Petar Mali]

Suppose that antiferromagnetic material have two sublattice. How can we measure magnetisation in sublattice A and in sublattice B? Maybe neutron scattering? How that work? Is NMR good solution maybe?

A SQUID device built right onto the material?

Zz.

Thanks for your answer. Is there some source on the internet where I could read more about it?

Yes, both certainly viable. Another one is muon spin rotation.

Do you have some reference for NMR?

You can measure the magnetic structure factor, S(q) using elastic neutron scattering. You then can propose a magnetic structure that will match S(q). It works just like measuring the lattice structure.
