Using Polarized Neutron Diffraction to study Magnetic Compounds | Prof. Domonique Luneau | Seminar

Polarized neutron diffraction and magneto-structural relationships in molecular magnetic compounds PND has proved to be particularly suitable for the study of magnetic molecular compounds and the determination of the spin density. This provides unique information on the paths of magnetic interactions and the nature of magnetic intra-or intermolecular coupling [1]. In this talk, we show on several examples how we can go beyond the spin density reconstruction and use the local susceptibility tensor approach [2] and study the magnetic anisotropy in molecular compounds This makes PND an excellent tool to help in the design of molecular-based magnets and especially single-molecule magnets for which strong uniaxial magnetic anisotropy is required.

(Accepted) ------------------------------ The International Institute for Sustainability with Knotted Chiral Meta Matter (WPI-SKCM2) is on a mission to introduce a new interdisciplinary research paradigm called “knotted chiral meta matter” (KCM2). Using this paradigm, our team of researchers cross-pollinates mathematical knot theory and chirality knowledge across disciplines and scales. This work includes the creation of designable artificial knot-like particles that exhibit highly unusual and technologically useful properties, which will both deepen our understanding of nature as well as be useful for technological innovation to solve global problems, such as climate change. While pursuing this research, we will create a testbed for research-based graduate education reforms in Japan & beyond, connecting young talent globally.
