Hace 6 días · Manganese is a chemical element; it has symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
9 de abr. de 2024 · The Jahn-Teller effect and corresponding orbit occupation result in a ferromagnetic exhagne interaction in CrX 2 Se 3. In Mn X 2 Te 3 , there is no Jahn-Teller effect and an...
14 de abr. de 2024 · The topology of the ground-state potential energy surface of M(CN)6 with orbitally degenerate 2T2g (M = TiIII (t2g1), FeIII and MnII (both low-spin t2g5)) and 3T1g ground states (M = VIII (t2g2), MnIII and CrII (both low-spin t2g4)) has been studied with linear and quadratic Jahn−Teller coupling models in the five-dimensional space of the εg and τ2g octahedral vibrations (Tg⊗(εg+τ2g ...
