Magnetic and Structural Studies of G‑Phase Compound Mn6Ni16Si7

Transition metal compounds with complex crystal structures tend to demonstrate interesting magnetic coupling resulting in unusual magnetic properties. In this work, the structural and magnetic characterization of a single crystal of the Ni-Mn-Si based G-phase compound, Mn₆Ni₁₆Si₇, grown by the Czochralski method, is reported. In this structure, isolated octahedral Mn₆ clusters form an fcc lattice. As each octahedron consists of eight …
