本文研究了类伊辛金属自旋玻璃在零温量子临界点附近近藤效应与RKKY相互作用之间的竞争。我们考虑各种物理量的平均场行为。在“量子临界制度”的非分析修正费米液体的行为被发现的比热和均匀的静态磁化率，而电阻率和NMR弛豫速率有一个非费米液体的温度依赖性。
In this paper we study the competition between the Kondo effect and RKKY interactions near the zero-temperature quantum critical point of an Ising-like metallic spin-glass. We consider the mean-field behaviour of various physical quantities. In the ‘quantum- critical regime’ non-analytic corrections to the Fermi liquid behaviour are found for the specific heat and uniform static susceptibility, while the resistivity and NMR relaxation rate have a non-Fermi liquid dependence on temperature.
