✦ Synopsis

Magnetizations were measured for both UNi I ~PdxGe (x = 0.0, 0.25, 0.5, 0.75) and UPd, ,.PtyGe (y = 0.0, 0.25, 0.5, 0.75, 1.0) systems. UNi 1 ~Pd~Ge shows a sinusoidal magnetic transition with TN~55K followed by ferromagnetic trans-formation below 40 K. Pd rich UPdl ~.Pt~.Ge undergoes a ferromagnetic state with T c lower than 60 K, while the Pt rich UPd~ PLGe compounds reveal cycloidal magnetic transition around 50 K. The mechanism by which various magnetic phases appear in UTGe (T = Ni, Pd, Pt) is considered to be due to competition of the exchange interactions in the bc-plane accompanied by a change in transition metals.
