Abstract
The electrical resistivity of LaB6 and LuB12 single crystals with high residual resistivity ratios has been measured down to 1.6 K. The temp erature dependence below 30 K, caused by phonon scattering, shows for both materials a T-n behaviour with n = 4.2+/-0.1 for LaB6 and n = 5.2 +/-0.1 for LuB12. From susceptibility measurements the superconducting transition temperature of LuB12 was determined to be 0.44 K, for the LaB6 sample with residual resistivity ratio of 160 no transition into the superconducting state was observed down to 5 mK.
