Multifunctional molecular magnets
Development of multifunctional molecular magnets where magnetic properties are combined to optical or dielectric properties are at the heart of this research theme. A particular interest is devoted to compound exhibiting magneto-optical or magneto-electric properties (multiferroicity).
The common characteristic of these properties is a chiral and polar crystal lattice space group. These compounds are therefore made with homochiral molecular bricks.[1-2]
An illustration of this is polarized emission observed for a chiral Dy(III) complex when this SMM is in a slow relaxation regime of its magnetization (see illustration).[3]
Such materials are promising for devices usable in quantum technologies.[4-5]
