Kondo effect - Wikipedia
In physics, the Kondo effect describes the scattering of conduction electrons in a metal due to magnetic impurities, resulting in a characteristic change i.e. a minimum in electrical resistivity with temperature. [1]
Kondo Effect - (Principles of Physics II) - Fiveable
The Kondo effect refers to the increase in electrical resistance of metals at low temperatures due to the scattering of conduction electrons by localized magnetic moments, typically from impurities or defects in the material.
2013年6月6日 · The Kondo effect is normally observed in very dilute magnetic alloys as a result of the interaction between the host conduction electrons and the magnetic impurity spins. In its ideal form, it is a single-impurity effect and leads to the rise of the electrical resistivity as the temperature is lowered down to zero temperature.
It provides a brief introduction to the history and main principles behind the e ect, touches on the theory that gave this e ect the Kondo name, presents two experimental examples of the Kondo e ect, and succinctly reviews its relevance in the physics world today.
The role of magnetic anisotropy in the Kondo effect - Nature
2008年9月21日 · Here we demonstrate the decisive role of magnetic anisotropy in the physics of Kondo screening. A scanning tunnelling microscope is used to simultaneously determine the magnitude of the spin,...

2011年10月21日 · 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)\)).
VBS The Kondo Effect – 16 The Impurity Question Given that we have the host metal at some filling, say the chemical potential is “mid-band” (µ = 0), what “happens” to the impurity d-level? Is the impurity level occupied? Is the impurity “magnetic”, i. e., does it retain a “spin”? Recap: What happens in a free ion?
Over the period of the last 50 years we have learned that the Kondo problem is not restricted to magnetically doped noble or divalent metals: it has turned out to be one of the most fundamental problems in solid state physics.
Kondo effect is a well known and widely studied phenomenon in condensed-matter physics, it continues to capture the imagination of experimentalists and theorists alike. The effect arises from the interactions between a single magnetic atom, such as cobalt, and the many electrons in an otherwise non-magnetic metal. Such an
Kondo Effect in Quantum Dots | Science - AAAS
1998年7月24日 · The Kondo effect is essentially a screening of the dot (or impurity) spin by nearby free electrons and so takes place only when the dot is magnetic. Below a characteristic temperature T K called the Kondo temperature, the unpaired electron in the dot hybridizes with the conduction band states in the leads.
