Abstract

We investigate flux-grown Sm-deficient SmxB6 (x<1) by global and local tools, including x-ray diffraction (XRD), electronic transport, and scanning tunneling microscopy (STM) and spectroscopy (STS). All these tools indicate a remarkable persistence of the SmB6 local structure in the flux-grown samples even for nominal Sm concentrations as low as x=0.75. As a consequence, the overall electronic properties of SmxB6, and particularly the surface conductance at low temperature, are only affected locally by the Sm deficiency.
