概要
- 論文の詳細を見る
The ground-state properties of the spin-1 / 2 RKKY Heisenberg spin glass are in-vestigated on the fcc lattice. Numerical diagonalization of finite-size systems and ex-trapolation to the infinite system suggest either that the correlation function decays ina power law<.5.?.5,>' -r ' "(j=0.02:0.09) or that there is a small but finite valueof the order parameter. From comparison with other theories, we prefer the formerpossibility of vanishing spin glass ordering.
