Design and Experiment of a Small High-Speed Liquid Jet Apparatus

Abstract

We investigate the unusual magnetic, thermodynamic and transport properties of nearly-critical, weakly-itinerant ferromagnets with the general formula UTX, where T = Rh, Co and X = Ge, Si. As a unique feature of these systems, we show how changes in the V df hybridization, which controls their proximity to a ferromagnetic instability, determine the evolution of the ground state magnetization, M 0 , the Curie temperature, T C , the density of states at the Fermi level, N(E F ), the T 2 resistivity coefficient, A, and the specific heat coefficient, γ . The universal aspect of our findings comes from the dependence on only two parameters: the transition metal T d bandwidth, W d , and the distance between the T d and U f band centers, C T d
