Magnetic Polarons and the Metal-Semiconductor Transition in (Eu,La)B6 and EuO: Raman Scattering Studies

C. S. Snow, S. L. Cooper, D. P. Young +3

We present inelastic light scattering measurements of EuO and Eu${}_{1-x}$La${}_x$B${}_6$ ($x$=0, 0.005, 0.01, 0.03, and 0.05) as functions of doping, B isotope, magnetic field, and te…
