LiNiO2: Quantum liquid or concentrated spin glass?

Abstract
From the magnetic and Mössbauer spectroscopy study of LiNi1−xFexO2 with x=0, 0.01, 0.05, and 0.10 evidence for strong ferromagnetic correlations and spin freezing at low temperatures was found, reminding many characteristic features of spin glass behavior in variance with models describing the ground state of LiNiO2 as a quantum liquid.
