Abstract
We examine the spatial dependence of the spin polarization arising from a magnetic impurity as well as the impurity-impurity interaction for impurities dissolved in an idealized two-dimensional metal. We find that the usual dependence of the oscillations in a three-dimensional metal is replaced by a dependence in a two-dimensional system, where is the Fermi wave vector, and is the distance from the impurity. Using this result we show that the temperature and concentration dependence of the thermodynamic properties of a magnetic-impurity system dissolved in a two-dimensional metal will, in the molecular-field approximation, be identical with that dissolved in a three-dimensional system. Similarly, the distance dependence of the screening charge from a nonmagnetic impurity in a metal changes from a (times an oscillating function) dependence in three dimensions to a dependence in two dimensions.
