Introduction to the Kondo Effect

摘要: Conduction measurements of magnetic systems at low temperature, like the present study 3d transition metal MePc on Ag(100) are closely intertwined with a phenomenon known as Kondo effect. Essentially it is coupling conduction electrons to impurity. Below critical so-called leads screening spin impurity due creation many-body singlet state. This gives rise typical sharp resonance in DOS Fermi level, which can be accessed experimentally by STS measurements. characteristic impurities non-magnetic surface. Hereby provides method for STM probe properties adatoms or molecules.
