The Kondo effect is an unusual scattering mechanism of conduction electrons in a metal due to magnetic impurities, which contributes a term to the electrical resistivity that increases logarithmically with temperature as the temperature T is lowered as log(T) (Scholarpedia).

Single-molecule magnets are a class of metalorganic compounds that show superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, single-molecule magnets exhibit magnetic hysteresis of purely molecular origin. Contrary to conventional bulk magnets and molecule-based magnets, collective long-range magnetic ordering of magnetic moments is not necessary (Wikipedia).

The advent of new technologies made possible study of electronic transport through quantum objects like single molecules, molecular wires, and quantum dots. The research of quantum transport opens new ways of understanding quantum-mechanical behaviour of strongly correlated systems.

Nanowires, molecules and even single atoms are a realization of low-dimensional quantum junctions. Naturally, the electric current can be thought to be a consequence of charge fluctuations. The fluctuations of electron’s spin come into play, when there is a spot in the junction where the Coulomb repulsion between electrons becomes very strong.
