Bloomberg 361Title: 50 years of BaCo2(AsO4)2 Abstract: BaCo2(AsO4)2 was among the group of transition-metal compounds discovered 50 years ago that attracted interest in quantum magnetism due to their low-coordination honeycomb lattice of magnetic ions and the easy-plane anisotropy. Its ground state, excitation spectra, and very low in-plane critical fields remained an enigma until recently. It was […]
