New Synthesis Route and Magnetic Structure of Tm<sub>2</sub>Mn<sub>2</sub>O<sub>7</sub> Pyrochlore
In this work, we present a new chemical route to synthesize Tm2Mn2O7 pyrochlore, which a compound that is thermodynamically unstable at ambient pressure. Differently from the reported in the past high-pressure synthesis of the same compound applying oxides as starting materials, we have obtained a pure Tm2Mn2O7 phase by a …
