Abstract

We report a systematic X-ray and 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 (↑↑↓↓) arrangement below ~ 50 K. In addition, short range magnetic correlations can be seen to persist until ~ 130 K.
