Observation of an antiferromagnetic quantum critical point in high-purity LaNiO3

Observation of an antiferromagnetic quantum critical point in high-purity LaNiO3

LaNiO3 is a strange metal, for reasons that are not well understood. Here, Liu et al. report evidence for scattering of charge carriers by antiferromagnetic quantum fluctuations in high-purity epitaxial thin films of LaNiO3, suggesting it is close to an antiferromagnetic quantum critical point.
