The quasi-particle excitations of a ferromagnet, near a quantum critical point are examined. The weak ferromagnetic state is described by the Hubbard model. The effects of emission of absorption of Goldstone modes on the quasiparticles is examined, as are the effects of the incoherent spin-flip exci
The alloy CePd 1Γx Rh x is a unique example undergoing quantum critical behavior between ferromagnetic CePd Γ°T C ΒΌ 6:6 KΓ and mixed valence CeRh. The negative curvature of T C Γ°xΓ holds up to x ΒΌ 0:6, followed by a positive tail with the lowest measured T C ΒΌ 0:25 K at x ΒΌ 0:80. We report on a detai
