Physical Review B-Condensed Matter and Materials Physics, 73(12). doi: 10.1103/PhysRevB.73.125119. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/6m418103

We present an infrared/optical study of the dynamics of the strongly correlated electron system YbIn1-x Agx Cu4 as a function of composition and temperature for x ranging from 0 to 1, and T between 20 and 300 K. YbIn1-x Agx Cu4 evolves from a mixed-v

We report the infrared charge dynamics of YbIn1-xAgxCu4 in a series of x- and T-dependent reflectivity measurements. Within the low-temperature coherent phase, characteristics of a low energy (0.25 eV) excitation appear to be controlled by the same K

Publikováno v: Hancock, JN; McKnew, T; Schlesinger, Z; Sarrao, JL; & Fisk, Z. (2004). Kondo scaling in the optical response of YbIn1-xAgxCu4. Physical Review Letters, 92(18), 186405-186401. doi: 10.1103/PhysRevLett.92.186405. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/69j6v3mq

The Kondo scaling in the infrared-frequency optical response measurments of the correlated system YbIn1-xAgxCu4was discussed. It was observed that the x-dependent variations in the frequency and strength of a low energy excitation were related to the
