Magnetostrictive Neel ordering of the spin-5/2 ladder compound BaMn2O3: distortion-induced lifting of geometrical frustration

M. Valldor, O. Heyer, A. C. Komarek +3

The crystal structure and the magnetism of BaMn${}_2$O${}_3$ have been studied by thermodynamic and by diffraction techniques using large single crystals and powders. BaMn${}_2$O${}_3$ is…
