With the presence of open-shell TM cations in the structure, there are many ways to orient the unpaired electrons. Hence, the starting point towards obtaining the bulk properties of LMNO is to find the correct ground state structure. Erroneous magnetic ordering assignment can lead to an increased computational cost, incorrect ground state energy and electronic structure. We have considered all possible magnetic orderings in the 56 atom conventional P 4 3 32 LMNO cell. The ground state magnetic ordering was calculated to be ferrimagnetic (FiM) with Mn↑ Ni↓, in line with experimental findings. More details can be found in Figure .
