In a recent work devoted to the magnetism of Li _2 CuO _2 , Shu et al (2017 New J. Phys. 19 , 023026) have proposed a ‘simplified’ unfrustrated microscopic model that differs considerably from the models refined through decades of prior work. We

A unique behaviour of the phase CoCu{sub 2}O{sub 3} was found both from CALPHAD calculations and directional solidification experiments. For elevated oxygen partial pressure the solidification mode changed from double-peritectic to a congruent meltin
