The effects of doping and pressure on the superconducting transition temperature ((Formula presented)) of Lu((Formula presented)(Formula presented))BC with A=Cu and V have been investigated. (Formula presented) was found to increase with Cu doping, but decrease with V doping, and pressure was observed to suppress all samples, doped or undoped, examined at a constant rate of ∼-0.17±0.3 K/GPa. The observations are not consistent with the predicted Fermi surface of LuNiBC residing at a density-of-states peak, and the pressure effect on (Formula presented) cannot be understood in terms of shift in the Fermi surface alone.
