Abstract
The stability of the Sr4Fe6O13 phase, and the phase changes taking place in the presence of Co, an discussed. Reported transport parameters are analys ed and discussed in relation to defects and phase changes in SrFe1.5-xCoxOz . A defect model is suggested that is in qualitative agreement with the obs erved transport parameters. It is suggested that defect ordering due to Co2 + ions is decisive for the transport properties.
