抄録

Slow spin fluctuations (v1012 s-1) observed by the muon spin relaxation technique in Yi-xScxMn2 exhibits a power law dependence on temperature (v ∝ Tα ), where the power converges asymptotically to unity (α → 1) as the system moves away from spin-glass instability with increasing Sc content x. This linear T dependence, which is common to that observed in LiV2O 4, is in line with the prediction of the 'intersecting Hubbard chains'' model for a metallic pyrochlore lattice, suggesting that the geometrical constraints to t2g bands specific to the pyrochlore structure serve as a basis of the d-electron heavy-fermion state.
