Superconductivity in LnFePO (Ln = La, Pr, and Nd) single crystals
R. E. Baumbach, J. J. Hamlin, L. Shu +3
Single crystals of the compounds LaFePO, PrFePO, and NdFePO have been prepared by means of a flux growth technique and studied by electrical resistivity, magnetic susceptibility an…
Charge dynamics in the normal state of the iron oxypnictide superconductor LaFePO
M. M. Qazilbash, J. J. Hamlin, R. E. Baumbach +2
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 i…
Superconductivity in single crystals of LaFePO
J. J. Hamlin, R. E. Baumbach, D. A. Zocco +2
Single crystals of the compound LaFePO were prepared using a flux growth technique at high temperatures. Electrical resistivity measurements reveal metallic behavior and a resistiv…
Recent Studies in Superconductivity at Extreme Pressures
James S. Schilling, James J. Hamlin
Studies of the effect of high pressure on superconductivity began in 1925 with the seminal work of Sizoo and Onnes on Sn to 0.03 GPa and have continued up to the present day to pre…
Pressure-induced Superconductivity in CaLi2
T. Matsuoka, M. Debessai, J. J. Hamlin +2
A search for superconductivity has been carried out on the hexagonal polymorph of Laves-phase CaLi2, a compound for which Feng, Ashcroft, and Hoffmann predict highly anomalous beha…
Superconductivity at 17 K in Yttrium Metal under Nearly Hydrostatic Pressures to 89 GPa
J. J. Hamlin, V. G. Tissen, J. S. Schilling
In an experiment in a diamond anvil cell utilizing helium pressure medium, yttrium metal displays a superconducting transition temperature which increases monotonically from Tc ? 3…
