In this paper we study the spin torque driven magnetization dynamics of metalic spin valve structures based on a free composite synthetic ferromagnet (SyF) that consists of two ferromagnetic layers coupled through a normal metal spacer. The magnetization can be excited into dynamical precessional states by an applied electric current at zero external magnetic field. This device can be used for nanoscale...
Resonances degrade the product's EMI or immunity performance at resonance frequencies. Near field scanning techniques, like EMI scanning or susceptibility scanning determine the local behaviour, but fail to connect the local behaviour to the system level behaviour. Resonating structures form part of the coupling paths, i.e., identifying them will aid in understanding system level behaviour of products...
Electrostatic discharge (ESD) can cause interference or damage in circuits in many ways e.g., by E- or H-field coupling or via conduction paths. Although we can roughly estimate the voltage and current at the injection point during an ESD event, the real offending parameter is mostly the ESD current spreading throughout the system. Those currents can be simulated if great simplifications of the system...
