ResumoThe magnetic phase diagram of the system ${\mathrm{CeCu}}_{2}$(${\mathrm{Si}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ge}}_{\mathit{x}}$${)}_{2}$ with 0\ensuremath{\le}x\ensuremath{\le}1 is studied by electrical transport, magnetic susceptibility, and neutron scattering measurements. The transition from heavy-fermion superconductivity in ${\mathrm{CeCu}}_{2}$${\mathrm{Si}}_{2}$ to the local moment type of antiferromagnetism in ${\mathrm{CeCu}}_{2}$${\mathrm{Ge}}_{2}$ is explored. The system reveals a rich phase diagram with up to three distinct transitions below 5 K. The nature of the phases is not fully resolved yet. \textcopyright{} 1996 The American Physical Society.
