The influence of Mn 2+ content on the magnetic properties was then analyzed by recording the hysteresis curves at 300 K using a superconducting quantum interference device (SQUID), as described in the experimental section. Magnetization values were normalized to the organic content measured by TGA (Figure in the S.I) and all the magnetic parameters are presented in Table average particle sizes, crystallite sizes, and morphologies, the cation distribution along tetrahedral and octahedral sites could be the key property ruling the ultimate magnetic properties , except for the sample with the highest Mn 2+ content (xEmpiric =1.40), where defects, associated with the concomitance of a reduced phase and Mn 3+ fraction, effectively impact their magnetic properties.
