Near coincidence of metal-insulator transition and quantum critical fluctuations: Electronic ground state and magnetic order in Fe${}_{1-x}$Co${}_x$Si

J. Grefe, P. Herre, Y. Hilgers +7

We present a detailed study of the electronic and magnetic ground state properties of Fe${}_{1-x}$Co${}_x$Si using a combination of macroscopic and microscopic experimental technique…
