Magnetism and segregation in Fe-Cr-Mn

Abstract
Fe-Cr-Mn alloys with 10 at. % Mn have similar structural and magnetic properties as Fe-Cr alloys, but have considerably higher Néel temperatures for the same Fe/(Fe+Cr) content ratio. When segregated, the high Néel temperatures of Fe-Cr-Mn alloys make it possible to investigate the magnetic nature of the Cr- and Fe-rich components. Resistivity and magnetization measurements show distinct features that correspond to a superposition of the properties of the individual segregated components.
