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…
