Intrinsic magneto-dielectric effect in the diluted magnetic ferroelectric fluoride BaMg1−Mn F4 (0≤x≤0.07)

The quest towards epitaxial BaMgF4 thin films: exploring MOCVD as a chemical scalable approach for the deposition of complex metal fluoride films

“…Although the pure compound doesn't exhibit ferromagnetism, it has been recently demonstrated that this property can be induced by substitutional doping of Mg by a magnetic transition metal ion such as Mn. 12,13 This yields a multiferroic material, i.e. ferro/antiferroelectric and ferro/antiferromagnetic properties coexist simultaneously exhibiting electromagnetic coupling.…”

“…These materials are considered as key components in the development of future technologies, for example, in memories and read-write electronic devices. 14 To date, BMF phases have been synthesized as bulk single crystals by the Bridgman method, 15 using Czochralski-basedgrowth 6,[16][17][18] and hydrothermal synthesis, 12,13,[19][20][21] or as nanocrystalline material. 22 Sol-gel techniques to synthesize polycrystalline BMF have also been reported, but in these reports BaF 2 and/or MgF 2 impurities were found.…”
