It was found that the charge-ordered phase of hte AlV2O4 spinel was rapidly suppressed and a charge-disorder phase grows up instead with Cr doping into the V site, yielding a two-phase-coexisting state in modestly Cr-doped samples. The magnetic ground state is a spin-glass state dominated by geometrical frustrtion low temperatures in the charge-ordered phase. Such a difference in magnetic properties can be attributed to the difference in dimensionality as a spin system etween the charge-ordered phase and the charge-disordered phase.
