Non Fermi liquid ground states in strongly correlated f-electron materials
- Univ. of California, San Diego, La Jolla, CA (United States); and others
Experimental efforts to characterize and develop an understanding of non Fermi liquid (NFL) behavior at low temperature in f-electron materials are reviewed for three f-electron systems: M{sub 1-x}U{sub x}Pd{sub 3} (M = Sc, Y), U{sub 1-x}Th{sub x}Pd{sub 2}Al{sub 3}, and UCu{sub 5-x}Pd{sub x}. The emerging systematics of NFL behavior in f-electron systems, based on the present sample of nearly ten f-electron systems, is updated. Many of the f-electron systems exhibit the following temperature dependences of the electrical resistivity {rho}, specific heat C, and magnetic susceptibility x for T {much_lt} T{sub 0}, where T{sub 0} is a characteristic temperature: {rho}(T) {approximately} 1 - aT/T{sub 0}, where a < 0 or > 0, C(T)/T {approximately} (-1/T{sub 0})ln(T/bT{sub 0}), and x(T) {approximately} 1 - c(T/T{sub 0}){sup 1/2}. In several of the f-electron systems, the characteristic temperature T{sub 0} can be identified with the Kondo temperature T{sub K}.
