Abstract
The residual molecular oxygen is responsible for a ferromagnetic coupling between the neighbouring lithium phthalocyanine π-radicals resulting in a septet spin-state. The intrinsic magnetic susceptibility is thermally activated up to 400 K. The properties of the system are shown to be consistent with the concepts of spin fluctuations introduced in itinerant magnetism.Keywords
