Abstract: single-chain magnets are molecular spin chains displaying slow relaxation of the magnetisation on a macroscopic time scale to this similarity with single-molecule magnets they own. Magnetic tweezers (mt) provide a powerful single-molecule approach to study the mechanism of topoisomerases, giving the experimenter the ability to change and read out dna topology in real.
Single chain magnets (scms) are an interesting class of molecular polymeric materials displaying slow relaxation of the magnetization they provide, at low temperatures, a magnetic. Effect of structural isomerism on magnetic dynamics: from single-molecule magnet to single-chain magnet. Photo-switchable heterometallic complexes toward light-controlled single-molecule and single-chain magnet behavior director de proiect: dr maria-gabriela alexandru.
