This clearly indicates that the negative value of dρ/dT in CdYb QCs is mainly due to the quasiperiodicity because these QCs are stoichiomeric compounds with a very narrow single phase range. Positive dρ/dT and anomalously large MR reported previously are found to be due to the existence of free Cd in the samples.
