Phase separation and pairing fluctuations in oxide materials
A. Bill, V. Hizhnyakov, R. K. Kremer +3
We investigate the microscopic mechanism of charge instabilities and the formation of inhomogeneous states in systems with strong electron correlations. It is demonstrated that wit…
Phase separation and proximity effects in itinerant ferromagnet-superconductor heterostructures
Christian Martens, Andreas Bill, Götz Seibold
Heterostructures made of itinerant ferromagnets and superconductors are studied. In contrast to most previous models, ferromagnetism is not enforced as an external Zeeman field but…
The role of canting and depleted-triplet minima in superconducting spin valve structures
Thomas E. Baker, Andreas Bill
The trilayer and pentalayer spin valve structures are revisited to determine the behavior of pair correlations and Josephson current when the magnetic layers are canted at arbitrar…
Cascading Proximity Effects in Rotating Magnetizations
Thomas E. Baker, Adam Richie-Halford, Ovidiu E. Icreverzi +1
We demonstrate two effects that occur in all diffusive superconducting-magnetic heterostructures with rotating magnetization: the reappearance of singlet correlations deep…
Long Range Triplet Josephson Current and Transition in Tunable Domain Walls
Thomas E. Baker, Adam Richie-Halford, Andreas Bill
The order parameter of superconducting pairs penetrating an inhomogeneous magnetic material can acquire a long range triplet component (LRTC) with non-zero spin projection. This st…
A universal high energy anomaly in angle resolved photoemission spectra of high temperature superconductors - possible evidence of spinon and holon branches
J. Graf, G. -H. Gweon, K. McElroy +10
A universal high energy anomaly in the single particle spectral function is reported in three different families of high temperature superconductors by using angle-resolved photoem…
