Abstract
We present data on the crystal structure and evolution of the electrical resistivity in lightly doped (, Y, Ce, and Nd) at ambient pressure and in under hydrostatic pressure. The upper charge density wave transition is suppressed by both doping and pressure with substitution-related disorder being the dominant mechanism for this suppression in the former case and the anisotropic pressure dependence of the unit cell dimensions (as seen in the ratio) prevailing in the latter case.
