Quantum nanomagnetism and related phenomena
In my talk I will review the experimental work done in the field of nanomagnets, emphasizing the description of quantum relaxation in magnetic nanoparticles and resonant spin tunneling in molecular magnets. I will start introducing the concepts of both exchange energy and magnetic anisotropy and the static and dynamic magnetic properties of nanoparticles. Then I will move to comment on the effect of quantum tunneling of magnetic poles in magnetic nanoparticles; quantum magnetic relaxation and the so called quantum resonant spin tunneling. The next step will be to explain phenomena related to spin tunneling such as quantum magnetic deflagration, the emission of superradiance by the magnetic flame and the possible use of nanomagnets as qubits. To finish, I will comment on the appearance of a new force of quantum origin in molecular magnets.
