Two Approaches to the Theory of Spin-Glasses: A Comparison with each other and with Experiment
We use the selfconsistent Mean-Random-Field (MRF) approximation to derive the properties of spin-glasses in the random molecular field approximation. For the Gaussian distributed exchange potentials discussed ...

Magnetic susceptibility of a two-component Kondo system: Proposed experiment to distinguish between various models for thec 2 dependence of χ
Recent experiments on the low-temperature magnetic susceptibility χ of very dilute concentrations of iron impurities in copper show a significant contribution proportional to the square of the iron impurity co...

Article
Many-impurity effects in a weakly interacting Kondo system: Comparison of theory with experiment
The theory of the many-impurity Kondo system developed in a previous paper is coupled with a statistical model, using a phenomenological relationship between the magnetic susceptibility χ and the effective Kon...

Chapter
Concentration Dependence of the Kondo Effect in a Random Impurity Potential
In a recent paper Tsay and Klein1,2 examined the two-impurity Kondo effect3 in the presence of an s—d Hamiltonian4,5 and an impurity—impurity exchange interaction of the form W01S0 · S1where W 01 ...

Heisenberg Model for Dilute Alloys in the Molecular Field Approximation
In the 1950’s several experiments were performed in which dilute concentrations of magnetic impurities were dissolved in a nonmagnetic metal host. These experiments were done prior to the discovery of the Kondo1 ...
