  Construction of molecule-based magnetic materials, which possess additional properties such as conductivity, photo reactivity or optical properties is now currently a challenging target. Specific goals for these molecule-based magnets include: i) the ability to design the molecular building blocks and to organize them in a solid for desired structure and/or dimensionality, and ii) optical transparency. The physical characteristic of current interest involves optical properties, particularly with respect to natural optical activity. When a magnet is characterized by optical transparency and chiral structure, the magnetic structure of the crystal is expected to be a chiral spin structure. These magnets display asymmetric magnetic anisotropy and magneto-chiral dichroism. This category of materials is not only of scientific interest, these materials also afford the possibility for use in new devices. When chiral molecule-based magnets are constructed, chirality must be controlled in the molecular structure as well as in the entire crystal structure. In this seminar, I would like to talk about recent results regarding construction, structure and magnetic and optical properties of molecule-based magnets with asymmetric structure.

* This talk will be given in Japanese.
