Electron paramagnetic resonance response and magnetic interactions in ordered solid solutions of lithium nickel oxides

EPR data of ordered solid solutions of lithium nickel oxides are reported as a function of the lithium content. The features of the signal and the EPR centre density are analysed by a model of dynamical trapping of holes in complexes. The possible origin of the interactions responsible for the magnetic ordering and some features of the transport properties are also discussed.
