N2 - Magnetism in the insulating BaFe 2Se 3 was examined through susceptibility, specific heat, resistivity, and neutron diffraction measurements. After formation of a short-range magnetic correlation, a long-range ordering was observed below T N∼255 K. The transition is obscured by bulk properties. Magnetic moments (a) are arranged to form a Fe 4 ferromagnetic unit, and each Fe 4 stacks antiferromagnetically. This block magnetism is of the third type among magnetic structures of ferrous materials. The magnetic ordering drives unusually large distortion via magnetoelastic coupling.
