NiMnGa is a prototypical Heusler alloy where structural, electronic, and magnetic degrees of freedom conspire to produce a large magnetic shape memory effect. The authors demonstrate how the complex interaction between these subsystems can be disentangled by using state-of-the-art time-resolved techniques.

Structurally unstable perovskites are predicted to be topological insulators but their stable structural forms are trivial band insulators

Structurally unstable compounds can be predicted to be topological insulators (TIs) but their stable structural forms are trivial band insulators. The authors illustrate the danger in such false positive predictions for the ABiO bismuth oxides that have been recently proposed as TIs in a hypothetical “perovskite” crystal structure-type. They show that the inversion of anti-bonding with bonding electron levels may destabilize the material and argue that to predict new candidate TIs by quantum atomistic modeling, one should simultaneously test structural stability and topological character of the candidate materials.
