“…The highly reducing atmosphere during thermal ammonolysis does not permit middle‐to‐late transition metals to form oxynitrides without being reduced to elemental metals or metal nitrides. For this reason, only a handful of magnetic oxynitrides are known including PrVO 2.24 N 0.76 , LaVO 2.09 N 0.91 ,9 NdVO 2 N,10 SrMoO 2 N,11 SrWO 2 N,12 Li 7.9 MnN 5− x O x ( x ≈1.7),13 and Mn 2 (MnTa 3 )N 6− x O 2+ x (0≤ x ≤1) 14. However, they do not exhibit any long‐range magnetic ordering (apart from that originating from A ‐site rare‐earth elements).…”

The synthesis, structure, and magnetic properties of a polar and magnetic oxynitride MnTaO2N are reported. High-pressure synthesis at 6 GPa and 1400 °C allows for the stabilization of a high-density structure containing middle-to-late transition metals. Synchrotron X-ray and neutron diffraction studies revealed that MnTaO2N adopts the LiNbO3-type structure, with a random distribution of O(2-) and N(3-) anions. MnTaO2N with an "orbital-inactive" Mn(2+) ion (d(5); S=5/2) exhibits a nontrivial helical spin order at 25 K with a propagation vector of [0,0,δ] (δ≈0.3), which is different from the conventional G-type order observed in other orbital-inactive perovskite oxides and LiNbO3-type oxides. This result suggests the presence of strong frustration because of the heavily tilted MnO4N2 octahedral network combined with the mixed O(2-)/N(3-) species that results in a distribution of (super)-superexchange interactions.

“…Perovskite materials have attracted much attention in many scientific fields for the composition diversity, easily available synthetic conditions and a variety of attractive properties 1,2 . For instance, hybrid organic-inorganic perovskite has widely applied in the fields of solar cells, light-emitting diodes, lasers, and photodetectors due to its longer charge diffusion lengths both for electrons and holes, higher carrier mobility and broad tunable bandgap (E g ) 3,4 .…”

The development of materials is one of the driving forces to accelerate modern scientific progress and technological innovation. Machine learning (ML) technology is rapidly developed in many fields and opening blueprints for the discovery and rational design of materials. In this review, we retrospected the latest applications of ML in assisting perovskites discovery. First, the development tendency of ML in perovskite materials publications in recent years was organized and analyzed. Second, the workflow of ML in perovskites discovery was introduced. Then the applications of ML in various properties of inorganic perovskites, hybrid organic–inorganic perovskites and double perovskites were briefly reviewed. In the end, we put forward suggestions on the future development prospects of ML in the field of perovskite materials.
