Resistivity of Mn${}_{1-x}$Fe${}_x$Si single crystals: Evidence for quantum critical behavior

C. Meingast, Q. Zhang, Th. Wolf +6

Resistivity measurements have been made on Mn${}_{1-x}$Fe${}_x$Si single crystals between 2 and 300K for $x$ = 0, 0.05, 0.08, 0.12 and 0.15. Fe doping is found to depress the magnetic…
