Abstract We present results of the magnetic susceptibility on high-quality single crystals of EuPd2(Si1−xGex)2 for Ge concentrations 0≤x≤0.105 performed under varying hydrostatic (He-gas) pressure 0≤p≤0.5 GPa. The work extends recent studies at ambient pressure demonstrating the drastic change in the magnetic response from valence-crossover behavior for x=0 and 0.058, to long-range antiferromagnetic (AFM) order below TN=47 K for x=0.105.
