Synthesis, structures and magnetic properties of the dimorphic Mn2CrSbO6 oxide

31 January, 2015 - 23:54

Dalton Trans., 2015, Advance Article
DOI: 10.1039/C4DT03849E, PaperAntonio J. Dos santos-Garcia, Elena Solana-Madruga, Clemens Ritter, David Avila-Brande, Oscar Fabelo, Regino Saez-Puche
Mn2CrSbO6-perovskite was synthesized at high pressure in order to stabilize the small Mn2+ cations on the A-perovskite site. Mn2CrSbO6-ilmenite polymorph can be prepared, starting from the perovskite, by a "hard-soft" phase transformation increasing the temperature at room pressure.
