dc.description.abstract | We report the temperature-dependent evolution of spin ordering and excitations of the frustrated tetragonal (c >a) spinel ZnMn2O4 across the two-dimensional antiferromagnetic transition. Muon spin relaxation indicates full development of ordered magnetic moments immediately below T-N = 62.7(2) K in spite of the apparent low-dimensional ordering. Using inelastic neutron scattering, we obtained the spin Hamiltonian accounting for the temperature-dependent spin excitations. The damped spin waves at high temperature exhibit a continuous increase in their lifetime on cooling across T-N. In contrast, the finite anisotropy gap appears suddenly below T-N indicating that single-ion anisotropy stabilizes the antiferromagnetic chains. We also observed the frustrated out-of-plane exchange contributing to the high-energy modes. | - |
