Spin glass behavior and oxidative catalytic property of Zn2MnO4 from a metathesis driven metastable precursor

Magnetic properties of Sn- and Mn-incorporated Co2TiO4 from single-step calcination

“…Our recent success in stabilizing Mn( iv ) containing cubic Zn 2 MnO 4 under ambient conditions prompted us to apply a similar synthetic strategy to obtain Co 2 TiO 4 and Sn- and Mn-substituted systems. 36 Such an approach becomes significant as one may stabilize most of the manganese ions in the +4 oxidation state, differing from the earlier report in which Jahn Teller active Mn 3+ was stabilized, leading to tetragonal global symmetry. 31 Hence, the cation distribution, their oxidation states (determined by X-ray photoelectron spectroscopy), and these systems’ magnetic and heat capacity properties will provide further information.…”
