Ceramic routes



Institut Néel is equipped with a large range of resistive and induction furnaces, that allows an important synthetic solid state chemistry activity including under controlled atmosphere. The studies of solid solutions in magnetic, magneto-optic, multiferroics compounds elaborated in various conditions allows to determine the relations between chemical composition, structure and properties. Recent studies deal with langasites system that show the effect of substitution on several cationic crystallographic sites AInstitut Néel is equipped with a large range of resistive and induction furnaces, that allows an important synthetic solid state chemistry activity including under controlled atmosphere. The studies of solid solutions in magnetic, magneto-optic, multiferroics compounds elaborated in various conditions allows to determine the relations between chemical composition, structure and properties. Recent studies deal with langasites system that show the effect of substitution on several cationic crystallographic sites A3BC2D2O14 (SPMCE – MCMF group). An other work developed by the Cristaux massifs – MCMF tech group with the SFCE – MCBTgroup show the possibility to induce ferromagnetism in semiconductors by non-magnetic impurities (SnO2 reacted with K2CO3 at low temperature).
