ABSTRACT
Molecular magnets have attracted considerable interest recently among researchers because they are considered to be ideal systems to probe the interface between classical and quantum physics as well as to study decoherence in nanoscale systems. ›e advances in nanoscience during the last decade have made it possible to design and fabricate a wide variety of nanosize objects, ranging from a couple of micrometers all the way down to a few tens of nanometers, where quantum e˜ects become important and give rise to new properties. One of the goals of miniaturization was the possibility of observing quantum tunneling e˜ects in mesoscopic systems. One source for such a task is the so-called single-molecule magnets (SMM) and antiferromagnetic molecular wheels, in which the spin state of the molecule is known to behave quantum mechanically at low temperatures.
