Observation of an antiferromagnetic quantum critical point in high-purity LaNiO$_3$

Posted by klaurent Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Changjiang Liu, Vincent F. C. Humbert, Terence Bretz-Sullivan, Gensheng Wang, Deshun Hong | Summary: Amongst the rare-earth perovskite nickelates, LaNiO$_3$ (LNO) is an exception. While the former have insulating and antiferromagnetic ground states, LNO remains metallic and non-magnetic down to the lowest temperatures. It is believed that […]
