Wireless power transfer (WPT) systems have emerged as a key technology for the future charging
infrastructure. Besides full system efficiency, the power densities of the transmission coils are key
We systematically study the performance of compact lumped element planar microwave Nb70Ti30N (NbTiN) resonators operating at 5 GHz in external in-plane magnetic fields up to 440 mT, a broad

Technical Description of the WMI Helium Pump
A vertical cross-section, a horizontal cross-section along the line A-B and a vertical cross-section of part of the pump systems is shown in the
Over the past two decades, the helium price has been strongly increasing. The reason is a growing demand and a change in supply chains. Although helium prices were doubling from 2002 to 2012, both

Master Thesis: Spin Pumping and Spin Wave Damping in Co25Fe75 Thin Film Heterostructures (2018) Ph.D.
We investigate the spin Hall magnetoresistance (SMR) at room temperature in thin-film heterostructures of antiferromagnetic insulating (0001)-oriented alpha-Fe2O3 (hematite) and Pt. We measure their
The ability to control the Gilbert damping which determines the lifetime of spin information is crucial for designing spintronic and magnonic devices. Thus, controlling the Gilbert damping parameter

Ph.D. Thesis: Scanning Microscopy and Momentum-Resolved Raman Scattering in Semiconductors
The scientific goals of MOQS are to perform experimental and theoretical quantum simulations of comparatively complex molecular structures as well as electron and energy transfer in molecular
Antiferromagnetic materials promise improved performance for spintronic applications as they are robust against external magnetic field perturbations and allow for faster magnetization dynamics
We describe the results of electronic Raman-scattering experiments in differently doped single crystals of YBCO and BiSCCO. The data in antiferromagnetic insulating samples suggest that at least the
