AB Herein we report the second transition-metal-only triple perovskite Mn3MnTa2O9, from high pressure-high temperature transformation of Mn4Ta2O9. It shows 1 : 2 Mn : Ta B-site order and a complex antiferromagnetic behavior with a collinear structure that modulates into a spin density wave. The high pressure phase presents a 25% band gap reduction compared to its multiferroic precursor, recoverable above 625 °C.
