Large magnetoelectric coupling near room temperature in synthetic Melanostibite Mn2FeSbO6. Angew. Chem.: Int. Ed. 2017, 56, 4438-4442. doi: 10.1002/anie.2016097621433-785110.1002/anie.201609762https://hdl.handle.net/20.500.14352/92965Multiferroic materials exhibit two or more ferroic orders and have potential applications as multifunctional materials in the electronics industry. A coupling of ferroelectricity and ferromagnetism is hereby particularly promising. We show that the synthetic melanostibite mineral Mn2FeSbO6 (R-3 space group) with ilmenite-type structure exhibits cation off-centering that results in alternating modulated displacements, thus allowing antiferroelectricity to occur. Massive magnetoelectric coupling (MEC) and magnetocapacitance effect of up to 4000% was detected at a record high temperature of 260 K. The multiferroic behavior is based on the imbalance of cationic displacements caused by a magnetostrictive mechanism, which sets up an unprecedented example to pave the way for the development of highly effective MEC devices operational at or near room temperature.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.1002/anie.201609762restricted access546High pressureMultiferroicNeutron diffractionIndirect magnetoelectric couplingRaman spectroscopyQuímica inorgánica (Química)Materiales2303.29 Elementos de Transición2210.28 Química del Estado Sólido2211.17 Propiedades Magnéticas2211.11 Propiedades de Transporte de Electrones2213.03 Altas Presiones
