- W2000717631 abstract "We study the ground state of heavy fermions by renormalization-group theory and numerical exact diagonalizations. Our observation is that the ferromagnetic state is unstable compared to the Kondo state and that the ferromagnetic Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction scales to a trivial one close to zero, while in contrast the antiferromagnetic RKKY interaction ${mathrm{J}}_{mathrm{ij}}$ grows as scaling proceeds. This explains why we observe no ferromagnetic ordering in heavy-fermion materials in zero field. The antiferromagnetic RKKY interactions produce effects to reduce the ensuremath{beta} functions ${mathrm{ensuremath{beta}}}_{mathrm{J}}$ensuremath{equiv}dJ/d lnD and compete with the Kondo effect. Scaling theory and the diagonalizations show that for small ${mathrm{J}}_{mathrm{ij}}$ensuremath{ll}${mathrm{T}}_{mathrm{K}}$ the low-energy scale is given by ensuremath{Delta}Eensuremath{approx}${mathrm{T}}_{mathrm{K}}$${mathrm{e}}^{mathrm{ensuremath{-}}mathrm{ensuremath{alpha}}{mathrm{J}}_{mathrm{ij}}}$, and for large ${mathrm{J}}_{mathrm{ij}}$ we have a power law ensuremath{Delta}Eensuremath{approx}(1/${mathrm{J}}_{mathrm{ij}}$${)}^{mathrm{ensuremath{alpha}}ensuremath{'}}$. In the intermediate regime where the Kondo and RKKY effects cancel each other, our results support the existence of a zero of ${mathrm{ensuremath{beta}}}_{mathrm{J}}$." @default.
