Journal Article
On the Relationship of Magnetism and Superconductivity in Materials Containing Partially Filled f Shells (Frontiers in Magnetism)
Journal ArticleDOI
Strain induced renormalization of transport properties in UPt 3 thin films
TL;DR: In this article, the growth of sputter deposited UPt3 thin films on Al2O3, LaAlO3 and SrTiO3 was investigated and strong deviations from the typical heavy-fermion characteristics in electronic transport properties like resistivity, magnetoresitivity and Hall-effect are attributed to changes of the hybridization between the localized 5f and itinerant states.
Journal ArticleDOI
Magnetism and superconductivity in Eu0.2Sr0.8(Fe0.86Co0.14)2As2 probed by 75As NMR
TL;DR: In this paper, the authors reported bulk superconductivity in Eu$ 0.2 + 2+ moments at 0.0 K in zero field with an antiferromagnetic ordering of Eu 2 + 2 moments at 2D AFM spin fluctuations.
Journal ArticleDOI
