Cation, magnetic, and charge ordering in MnFe(3)O(5)

The recently-discovered high pressure material MnFe(3)O(5) displays a rich variety of magnetically ordered states on cooling. Fe spins order antiferromagnetically below a Néel transition at 350 K. A second transition at 150 K marks Mn spin order that leads to spin canting of some of the Fe spins and...

description The recently-discovered high pressure material MnFe(3)O(5) displays a rich variety of magnetically ordered states on cooling. Fe spins order antiferromagnetically below a Néel transition at 350 K. A second transition at 150 K marks Mn spin order that leads to spin canting of some of the Fe spins and ferrimagnetism. A further transition at 60 K is driven by charge ordering of Fe(2+) and Fe(3+) over two inequivalent Fe sites, with further canting of all spins. Electrical resistivity measurements reveal semiconducting behaviour in MnFe(3)O(5) with a change in activation energy at 285 K.
