SUMMARY

This discussion focuses on measuring magnetisation in antiferromagnetic materials with two sublattices, specifically sublattice A and sublattice B. The participants confirm that techniques such as neutron scattering, nuclear magnetic resonance (NMR), and muon spin rotation are effective methods for this purpose. They emphasize the use of elastic neutron scattering to measure the magnetic structure factor, S(q), which helps in proposing a magnetic structure that aligns with the measured data.

PREREQUISITES
  • Understanding of antiferromagnetic materials and their sublattice structures
  • Familiarity with neutron scattering techniques
  • Knowledge of nuclear magnetic resonance (NMR) principles
  • Basic concepts of muon spin rotation methods
NEXT STEPS
  • Research the principles of elastic neutron scattering and its applications in magnetism
  • Explore the fundamentals of nuclear magnetic resonance (NMR) in solid-state physics
  • Investigate muon spin rotation techniques and their relevance in measuring magnetic properties
  • Study the magnetic structure factor, S(q), and its significance in characterizing magnetic materials
USEFUL FOR

Researchers in condensed matter physics, materials scientists, and anyone involved in the study of magnetic properties in antiferromagnetic materials.

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?

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.
