Abstract The compounds Fe3−x Mn x Si exhibit a complex magnetic behavior for 0.6⩽x⩽1.75 involving ferromagnetic ordering followed by a reordering at lower temperature. Measurements of the thermal expansion α and the specific heat C p show only a weak anomaly at the Curie temperature, T C, whereas a large, relatively sharp peak occurs at the magnetic reordering temperature, T R. Thermal expansion measurements for the Fe2.2Mn0.8Si compound made about T R are indicative of long-range ordering that can be suppressed in an applied field of ∼0.4T. Magnetization measurements show that low fields, 1–2 mT, strongly influence the bulk magnetization. Irreversible magnetization behavior, similar to that in spin-glass systems, is displayed.
