In magnetic shape memory Heusler alloys, the premartensite phase is believed to be a precursor state of the martensite phase with preserved austenite phase symmetry. Here, the authors show that the premartensite is a stable phase with its own crystal

The control of different types of magnetic order is central to the study and development of spintronic devices. Here, the authors evidence an exchange-stabilized helix state with a low energy barrier for reversal in a room-temperature antiferromagnet

The origin of incommensurate structural modulation in Ni-Mn based Heusler-type magnetic shape-memory alloys (MSMAs) is still an unresolved issue in spite of intense focus on it due to its role in the magnetic field induced ultrahigh strains. In the a

Momentum resolved inverse photoemission spectroscopy measurements show that the dispersion of the unoccupied bands of Ni2MnGa is significant in the austenite phase. Furthermore, in the martensite phase, it is markedly reduced, which is possibly relat

We address the electron transport characteristics in bulk half-Heusler alloys with their compositions tuned to the borderline between topologically nontrivial semimetallic and trivial semiconducting phases. Accurate first-principles calculations base
