The intermetallic compound Pr1-x-yLaxPbyTe shows a wide spectrum of physical phenomena. Depending on the metallurgical composition as function of x and y, the compound changes its behavior from nuclear magnetic order to super- or semiconductivity. In addition, there are interesting interplay effects between these ground states. In consequence, Pr1-x-yLaxPbyTe may serve as an interesting material for quantum-computing applications. In this contribution, we focus on our recent investigation of the magnetic properties of Pr1-yPbyTe. We present data of the magnetisation taken at 1.8 K < T < 350 K for various compositions y = 0, 90, 99, 99.9 %, i.e. turning the system from a van Vleck paramagnet, y = 0, into a doped semiconductor, y = 99.9 %.
