Dynamic Exchange Coupling in Magnetic Bilayers [PDF]
Physical Review Letters, 2003 A long-ranged dynamic interaction between ferromagnetic films separated by normal-metal spacers is reported, which is communicated by nonequilibrium spin currents. It is measured by ferromagnetic resonance (FMR) and explained by an adiabatic spin-pump theory. In FMR the spin-pump mechanism of spatially separated magnetic moments leads to an appreciable

An Automatic Coil Design Method for Wireless Power Transfer Systems by Current Distribution Analysis
IEEE Access, 2023 The reduction of coil design cost is essential to integrating wireless power transfer (WPT) systems in electronic devices. However, the power transfer efficiency of WPT systems is influenced by operating conditions, such as the surrounding material and ...

Diffusion in a Strongly Coupled Magnetized Plasma [PDF]
Physical Review Letters, 2011 A first-principle study of diffusion in a strongly coupled one-component plasma in a magnetic field B is presented. As in a weakly coupled plasma, the diffusion coefficient perpendicular to the field exhibits a Bohm-like 1/B-behavior in the strong-field limit, but its overall scaling is substantially different. The diffusion coefficient parallel to the
