Magnetic resonance is a widely established phenomenon that probes magnetic properties such as damping and anisotropy. Even though the typical frequency of magnet ranges from gigahertz to terahertz, experiments also report near zero in large class magnets. Here we revisit this by analyzing symmetry system find $\ensuremath{\omega}$ follows universal power law $\ensuremath{\omega}\ensuremath{\pro...

The results of a study low-frequency ferromagnetic resonance in system two overlapping permalloy disks by magnetic force spectroscopy are presented. It is shown that the resonant frequency gyrotropic mode oscillations vortices this significantly depends on vorticity their shells. experimental dependences frequencies various states external field qualitatively consistent with micromagnetic model...

A magnetic vortex core in a ferromagnetic circular nanodot has a resonance frequency originating from the confinement of the vortex core. By the micromagnetic simulation including the spin-transfer torque, we show that the vortex core can be resonantly excited by an AC (spin-polarized) current through the dot and that the resonance frequency can be tuned by the dot shape. The resistance measure...

— In order to obtain exact values of the spectroscopic splitting factor in pure iron along the [100] and [111] crystallographic directions, measurements of ferromagnetic resonance in whisker type single crystals have been performed in the frequency range 12 470 GHz, at room temperature. The results show that the ̂ -factor is independent on frequency in the given range and yield the value g = 2.0...

A variety of neurons and synapses shows a maximal response at a preferred frequency, generally considered to be important in shaping network activity. We are interested in whether all neurons and synapses in a recurrent oscillatory network can have preferred frequencies and, if so, whether these frequencies are the same or correlated, and whether they influence the network activity. We address ...

Recently we reported experimental and simulation results on an increase in resonance frequency of a SAW resonator caused by mass loading of micropillars made of SU-8, attached normal to the surface of the resonator. We concluded that SAW resonator and the SU-8 micropillars in unison form a system of coupled resonators. We have now extended this work and performed a finite element method simulat...
