R. Spolenak et al., (FE,MN)SI - TRANSITIONS FROM A MAGNETIC TO A NONMAGNETIC STATE AND FROM METALLIC TO SEMICONDUCTING BEHAVIOR, Journal of magnetism and magnetic materials, 158, 1996, pp. 715-716
The pseudobinary series (FexMn1-x)Si shows a transition from an insula
tor for x = 1 to a metallic state with long range magnetic order at th
e Mn-rich side. This behaviour can be attributed to the shift of the F
ermi energy across a narrow gap into a region of high density of state
