Abstract

Abstract The heavy-fermion metal CePd 1 - x Rh x evolves from ferromagnetism at x = 0 to a non-magnetic state at some critical concentration x c . Utilizing the quasiparticle picture and the concept of fermion condensation quantum phase transition (FCQPT), we address the non-Fermi liquid (NFL) behavior of ferromagnet CePd 1 - x Rh x and show that it coincides with that of antiferromagnets YbRh 2 ( Si 0.95 Ge 0.05 ) 2 and CeCoIn 5, paramagnets CeRu 2Si 2 and CeNi 2Ge 2 and 2D 3He. We show that the NFL behavior is independent of the peculiarities of specific alloy and universal. Our study of the NFL behavior allows us to calculate the magnetoresistance of CeCoIn 5. Obtained results are in good agreement with facts and reveal a new scaling behavior of magnetoresistance.
