Evidence for 2-4 pairing in the (La,Ca) (Cr,Co)O3 series
Description
LaCrO3 and LaCoO3 are believed to be p-type small-polaron conductors. The carrier concentration in these materials is determined from Heikes' Formula. As Co is substituted for Cr, the carrier concentration increases. For LaCoO3, approximately 50% of the Co ions act as carriers. This is attributed to the self compensation of Co3+ into Co2+ and Co4+. The effect of Ca doping is discussed
