## Abstract The La~0.67~Ca~0.33~Mn~0.94~^57^Fe~0.06~O~3~ compound was studied using powder X‐ray diffraction, VSM magnetometry, four‐probe resistance measurements and ^57^Fe Mössbauer spectroscopy. The Mössbauer measurements were performed between 15 K and 850 K and showed good agreement between Cu
