Disorder of magnetic cations usually suppresses long-range spin order: the Curie or Néel temperature drops rapidly, and a spin glass state often results at high disorder levels. However, we have successfully synthesized La(Cr1/3Mn1/3Fe1/3)O3 perovskite with a long range spin-canted antiferromagnetic transition obtained by neutron diffraction. Nonetheless, a lower temperature magnetic transitionwith short range order and competing ferro-antiferromagnetic interactions character is evidenced with AC susceptibility measurements. No sign of this second transition could be detect in the neutron data. With the help of muon spin relaxation we will be able to uncouple the distinct contributions.
