Abstract
My comments concern the error in the lattice parameters and chemical composition of BiHoZnCeO6 perovskite published in the commented paper. The most probable composition of the studied sample is CeO2:Bi,Ho,Zn.
The source flagged this abstract for review. Check formulas and completeness against the original publication.
