Abstract

We discuss a mechanism leading to heavy-fermion behavior and quasi-onedimensional magnetism based on the charge-ordering transition out of a threedimensional homogeneous mixed- valence state. We focus the discussion on the realization of this scenario in YD4AS3 and the P- and Sb-substituted mixed compounds. We present recent experimental results on the low- temperature magnetic susceptibility and specific heat in an applied magnetic field. At temperatures below IK, we have observed spin glass behavior due to a small interchain coupling and disorder.
