Popis: We present a reinvestigation of the complex magnetic phase diagram of the heavy-fermion system Ce(Cu1-xNix)2Ge2 by employing measurements of the specific heat, C(T), and thermal expansion, α(T), on high-quality single crystals with x = 0, 0.02, 0.05, 0.5 and 0.8 in magnetic fields B ⩽ 8T. In addition to what was observed in polycrystalline samples multiple phase-transition anomalies could be resolved in these single crystals for x < 0.5 and 1.5 K
