AC Kolloquium - Professor Dr. Selvan Demir Organometallic Single-Molecule Mangets Containing Radicals and Bismuth Single-molecule magnets (SMMs) are molecules that possess an energy barrier to spin inversion, giving rise to slow magnetic relaxation and magnetic hysteresis. To realize their intriguing potential applications, ranging from molecular spintronics, quantum computing, to high-density information storage, spin-reversal barriers (Ueff) and magnetic blocking temperatures (TB) must be increased. Lanthanide ions are especially well-suited for the design of SMMs due to their large magnetic moments and magnetic anisotropy that originate from strong spin-orbit coupling of the 4f orbitals. One effective methodology to boost blocking temperatures of multinuclear compounds is to generate strong magnetic exchange between lanthanide centers using radical bridging ligands. https://www.chemie.uni-bonn.de/lu/de/lu-events/ac-kolloquium-professor-dr-selvan-demir https://www.chemie.uni-bonn.de/lu/++resource++plone-logo.svg
