Long- and short-range magnetism in the frustrated double perovskite Ba2MnWO6
Abstract
The structural and magnetic properties of the face-centered-cubic double perovskite Ba<sub>2</sub>MnWO<sub>6</sub> were investigated using neutron powder diffraction, DC magnetometry, muon spin relaxation, and inelastic neutron scattering. Ba<sub>2</sub>MnWO<sub>6</sub> undergoes type II long-range antiferromagnetic ordering at a Néel temperature of 8(1) K with a frustration index, f ≈ 8. Inelastic neutron scattering was used to identify the magnetic coupling constants J1 and J2, which were found to equal -0.080 and -0.076 meV, respectively. This indicates that both of the magnetic coupling constants are antiferromagnetic with similar magnitudes, which is in contrast to other known 3d metal double perovskites of the form Ba<sub>2</sub>MWO<sub>6</sub>. Above the Néel temperature, muon spin-relaxation measurements and inelastic neutron-scattering techniques identify a short-range correlated magnetic state that is similar to that observed in the archetypical face-centered-cubic lattice antiferromagnet MnO.
