Heavy fermion quantum criticality: The party is just beginning

作者：Yi-Feng Yang

摘要：Recently,Nature reported the discovery of a ferromagnetic quantum critical point(FM QCP)in the heavy fermion compound CeRh6Ge4[1].This is the first discovery of such kind in a stoichiometric compound.The FM order is suppressed at a critical pressure of 0.8 GPa,beyond which the ground state turns into a Fermi liquid.Previously,Science had also reported the observation of a FM QCP,albeit in the doped compound YbNi4(P0.92As0.08)2[2].
