Özet

The magnetic structures of the La0.65Nd0.35Mn 2Si2 have been investigated by powder neutron diffraction between 5 and 350 K. According to magnetic measurements this compound shows multiple magnetic phase transitions. Neutron diffraction indicates a canted ferromagnetic structure above 220 and below 46 K. Between 50≤T≤70K there is a mixed phase where canted ferromagnetic and antiferromagnetic structure coexist. Moreover, La0.65Nd0.35Mn2Si 2 has a two-step magnetic transition from an antiferromagnetic to ferromagnetic state between 65 and 22 K. This two-step transition had not been observed so far and in this study it is studied in depth. © 2011 Elsevier B.V.
