摘要：

The measurements on magnetization (M), resistivity (rho) and specific heat (C) were carried out for the ferromagnetic CeTi1-x NixGe3 (0.0 <= x <= 0.45) system. It was found that the Curie temperature, T-C, decreases with increasing Ni content, x, and reaches zero kelvin near a critical content x(cr) = 0.44. A new phase diagram is constructed based on these measurements. The non-Fermi liquid (nFL) behavior in rho(T), and log(T-0/T) relationship in C/T in the samples near xcr, demonstrate that strong spin fluctuation emerges in these samples, indicating that they are near a quantum critical point (QCP). Our results indicate that CeTi1-x NixGe3 may provide another platform to study exotic quantum phenomena near ferromagnetic QCP.
