Quantum phase transition in itinerant-electron ferromagnet system U(Co1-xOsx)Al
Original language description
We report the magnetic phase diagram of an itinerant-electron ferromagnetic system, U(Co1-xOsx)Al, derived from the AC susceptibility and DC magnetization. The quantum phase transition point at which the ferromagnetic transition temperature becomes 0 K is estimated to be located at x = 0.004. The tricritical point is also estimated to be located at x = 0.0065, T = 11 K. We also observed a non-Fermi liquid behavior near the quantum phase transition point: the electrical resistivity in the paramagnetic region is proportional to T3/2 rather than to T5/3 that is predicted at the quantum critical point. The T3/2 dependence is observed in some other itinerant-electron magnets. We discuss the possible mechanisms applied to these compounds.n
