Experimental and theoretical study of field-dependent spin splitting at ferromagnetic-insulator-superconductor interfaces
P. Machon, M. J. Wolf, D. Beckmann +1
We present a combined experimental and theoretical work that investigates the magnetic proximity effect at a ferromagnetic-insulator - superconductor (FI-S) interface. The simulati…
Spin-flip Enhanced Thermoelectricity in Superconductor-Ferromagnet Bilayers
A. Rezaei, A. Kamra, P. Machon +1
We study the effects of spin-splitting and spin-flip scattering in a superconductor (S) on the thermoelectric properties of a tunneling contact to a metallic ferromagnet (F) using…
Violation of non-interacting -representability of the exact solutions of the Schrödinger equation for a two-electron quantum dot in a homogeneous magnetic field
M. Taut, P. Machon, H. Eschrig
We have shown by using the exact solutions for the two-electron system in a parabolic confinement and a homogeneous magnetic field [ M.Taut, J Phys.A{\bf 27}, 1045 (1994) ] that bo…
Fully spin-dependent boundary condition for isotropic quasiclassical Green's functions
P. Machon, W. Belzig
Transport in superconducting heterostructures is very successfully described with quasiclassical Green's functions augmented by microscopically derived boundary conditions. However…
Nonlinear thermoelectric effects in high-field superconductor-ferromagnet tunnel junctions
S. Kolenda, P. Machon, D. Beckmann +1
Thermoelectric effects result from the coupling of charge and heat transport, and can be used for thermometry, cooling and harvesting of thermal energy. The microscopic origin of t…
Giant thermoelectric effects in a proximity-coupled superconductor-ferromagnet device
P. Machon, M. Eschrig, W. Belzig
The usually negligibly small thermoelectric effects in superconducting heterostructures can be boosted dramatically due to the simultaneous effect of spin splitting and spin filter…
