Abstract

Heusler compounds are a remarkable class of intermetallic materials with wide-ranging and tunable properties. The Mn2RuSn Heusler compound was reported as an L21B-type cubic phase, a = 0.62195 nm, distinguishing from the original L21 structure (or L21A-type). The L21B-type structure is a disordered variant of the inverse Heusler structure, XA-type (Prototype-CuHg2Ti, space group No. 216, F4–3m).

In our recent work [1], we observed a new modulated structure derived from the XA-type structure and its orthogonal domains in the Mn2RuSn Heusler alloy. The structural characterization was carried out using selected-area electron diffraction (SAED), transmission electron microscopy (TEM), dark-field (DF) imaging, and high-resolution transmission electron microscopy (HRTEM) imaging techniques.
