Osmium pyrochlore compounds provide a unique opportunity to study the interplay between the Coulomb correlation and spin-orbit interaction that may lead to novel all-in-all-out (AIAO) spin structure. We propose muSR study of spin dynamics which is strongly coupled with charge carriers on the verge of metal-insulator transition to elucidate the electronic property of the AIAO antiferromagnet.
