We report the results of dc and ac magnetization measurements as a function of temperature (1.8 - 300 K) for the spin-chain compound, Ca3CoRhO6, which has been recently reported to exhibit a partially disordered antiferromagnetic (PDAF) structure in the range 30--90 K and spin-glass freezing below 30 K. We observe an unexpectedly large frequency dependence of ac susceptibility in the T range 30--90 K, typical of superparamagnets. In addition, we find that there is no difference in the isothermal remanent magnetization behavior for the two regimes below 90 K. These findings call for more investigations to understand the magnetism of this compound.
