Charge dynamics in the normal state of the iron oxypnictide superconductor LaFePO (2008)
Qazilbash, M. M., Hamlin, J. J., Baumbach, R. E., Maple, M. B., Basov, D. N.
We present the first infrared and optical study in the normal state of ab-plane oriented single crystals of the iron-oxypnictide superconductor LaFePO. We find that this material is a low carrier...

Electrical resistivity $\rho$, specific heat C, and magnetic susceptibility $\chi$ measurements made on the filled skutterudite CeRu_4As_{12} reveal non-Fermi liquid (NFL) T - dependences at low T,...
Effect of annealing on glassy dynamics and non-Fermi liquid behavior in UCu_4Pd (2005)
MacLaughlin, D. E., Rose, M. S., Anderson, J. E., Bernal, O. O., Heffner, R. H., Nieuwenhuys, G. J., ...
Longitudinal-field muon spin relaxation (LF-muSR) experiments have been performed in unannealed and annealed samples of the heavy-fermion compound UCu_4Pd to study the effect of disorder on non-Fermi...
