H. Miki et al., FERROMAGNETIC-ANTIFERROMAGNETIC TRANSITION OF ITINERANT-ELECTRON MAGNETS MN3-XFEXSI, Physica. B, Condensed matter, 237, 1997, pp. 465-466
By combining both neutron diffraction and magnetization measurements t
he magnetic phase diagram is completed for Mn3-xFexSi system. The anti
ferromagnetism is realized in x < 1.25, and then ferromagnetism appear
s in x greater than or equal to 1.25. The Neel temperature increases g
radually with increasing x, and the Curie temperature for x > 1.25 see
ms to continue smoothly from the value of T-N. In the low temperature
region for x greater than or equal to 1.25, canting ferromagnetism tak
es place.
