Critical properties of the S=1 spin dimer compound Ba3Mn2O8
S. Suh, K. A. Al-Hassanieh, E. C. Samulon +8
Ba3Mn2O8 is a hexagonally coordinated Mn5+ S=1 spin dimer system with small uniaxial single-ion anisotropy. 135,137Ba NMR spectroscopy is used to establish the lower critical field…
Asymmetric quintuplet condensation in the frustrated S=1 spin dimer compound Ba3Mn2O8
E. C. Samulon, Y. Kohama, R. D. McDonald +5
Ba3Mn2O8 is a spin-dimer compound based on pairs of S = 1, 3d2, Mn5+ ions arranged on a triangular lattice. Antiferromagnetic intradimer exchange leads to a singlet ground state in…
Singlet-triplet dispersion reveals additional frustration in the triangular dimer compound BaMnO
M. B. Stone, M. D. Lumsden, S. Chang +3
We present single crystal inelastic neutron scattering measurements of the S=1 dimerized quasi-two-dimensional antiferromagnet BaMnO. The singlet-triplet dispersion rev…
