Dissertation/Thesis Abstract

Magnetic penetration depth analysis of unconventional superconductors
by Vandervelde, Daniel John, Ph.D., University of Illinois at Urbana-Champaign, 2008, 104; 3337979
Abstract (Summary)

We present magnetic penetration depth measurements on various superconducting materials using a self-inductive, tunnel-diode based oscillator technique down to ∼100 mK. The materials measured consisted of the skutterudites LaRu4Sb12 and LaOs4Sb 12, the heavy fermion superconductor CeIrIn5, a series of materials CeRh1-xIrxIn5, CeCoIn5 with two different dopants, Sn and Cd, and the layered dichalcogenide TiSe2 doped with copper. We seek to study the impact of antiferromagnetism and the presence of a quantum critical point on superconductivity. We also seek to characterize the superconductivity and compare to similar materials. Additionally we seek to study how superconductivity arises from novel methods such as charge density waves.
