The recent discovery of a pressure-induced ferromagnetic (FM) quantum critical point (QCP) and strange metal behavior in the heavy fermion metal CeRh6Ge4 [1] has attracted considerable interests. In this talk, I will present our progresses on elucidating its possible origins [2-5], including probing the nature of ferromagnetism, the roles of anisotropy and non-centrosymmetric structure on FM QCP, and the effects of disorder on strange metal behavior. Furthermore, I will also present a novel scenario of pressure-induced superconductivity in the Kondo ferromagnet Ce2CoGe5, where the FM order is converted to antiferromagnetic (AFM) order at 1.2 GPa, followed by an AFM QCP around 3.2 GPa, and unconventional superconductivity above 5GPa [6].
