We have measured specific heat in magnetic fields, magnetization at ambient and high pressures and magnetostriction of Ce_5Si_3 and its alloy system (Ce_<1-x>-*La.)_5Si_3. As temperature is lowered, the systems for x < x_c ~ 0.15 undergo successive phase transitions, while those for x > x_c exhibit only a spin-glass transition. From the obtained experimental results, we have constructed phase diagrams, magnetic field versus temperature for Ce_5Si_3 and temperature versus La-concentration for (Ce_<1-x>_.La_x)_5Si_3. The measurements of the magnetization have revealed that the metamagnetism occurs for field directions of H ‖ a as well as H ‖ c. We discuss an origin of the metamagnetism on the basis of a crystalline electric field model and thermodynamic analysis.
