Magnetic Ordering in a Frustrated Bow-Tie Lattice



Laura J. Vera Stimpson, Efrain E. Rodriquez, Craig Brown, Gavin B. G. Stenning, Marek Jura, Donna C. Arnold


We report a systematic elastic and inelastic powder neutron diffraction study of the geometrically frustrated material, Ca2Mn3O8. Ca2Mn3O8 exhibits a "bow-tie" like connectivity of Mn4+ with Ca2+ occupying octahedral sites between MnO6 layers. Magnetic refinements of neutron powder diffraction data indicate that the spins order with a canted four sub-lattice-like (up arrow up arrow down arrow down arrow}) arrangement below approximately equal} 50 K. In addition, short range magnetic correlations can be seen to persist, until approximately equal} 130 K. Inelastic data demonstrates that frustration results in the dynamic motion of the spins even below TN and provides evidence of both "spin-flow" and "chain-flip" phenomena.
