NiTi shape-memory transformations: minimum-energy pathways between austenite, martensites, and kinetically-limited intermediate states
N. A. Zarkevich, D. D. Johnson
NiTi is the most used shape-memory alloy, nonetheless, a lack of understanding remains regarding the associated structures and transitions, including their barriers. Using a genera…

Anomalous magneto-structural behavior of MnBi explained: a path towards an improved permanent magnet
N. A. Zarkevich, L. -L. Wang, D. D. Johnson
Low-temperature MnBi (hexagonal NiAs phase) exhibits anomalies in the lattice constants (a, c) and bulk elastic modulus (B) below 100 K, spin reorientation and magnetic susceptibil…
