Transition metal compounds that exhibit quantum magnetic states or whose dielectric properties are coupled to magnetic properties (magnetoelectric or type II multiferroic materials) are studied. Their crystal structures are analogous to those of minerals: wolframite for Mn(W,Mo)O4<\/sub>, karpenkoite for the pyrovanadate Co3V2O7<\/sub>(OH)2<\/sub>.2H2O<\/sub>, vesignieite for the orthovanadate BaCo3<\/sub>(VO4<\/sub>)2<\/sub>(OH)2<\/sub>, perovskite for the compounds (Ba,Sr)(Co,Ni)Sb2O9<\/sub>. In these materials, the metals carrying magnetic moments form lattices of particular geometries (chain, kagome, triangular, honeycomb, face-centered cubic) that give unusual magnetic properties. Our experimental approach consists in preparing materials by various methods, characterizing them, understanding the properties (magnetic, in particular) and the relationships between these properties, the composition, the crystalline structure and the microstructure or morphology of the material. <\/p>\n
