We succeeded in growing single crystals of the series of EuCu(Ge $_{1-x}$ Si) compounds.Physical property measurements demonstrate a maximum of the antiferromagnetic transition temperature appears at . Antiferromagnetism then disappears around followed by a heavy-fermion formation at higher concentrations. These observations follow the Doniach phase diagram as a function of .
