A magnetic susceptibility study of defect formation in the LiCoO2 complex oxide

The LiCoO2 complex oxide was for the first time treated as a variable compo sition compound capable of oxygen exchange with the gas phase even at low t emperatures. A detailed magnetochemical study was performed to distinguish between inherited defects and defects formed in exchange with the gas phase directly during magnetic susceptibility measurements. Conclusions on the n ature of the defects were drawn and the thermodynamic parameters of defect formation were estimated.
