We measured ferromagnetic resonance of a single submicron ferromagnetic strip, embedded in an on-chip microwave transmission line device. The method used is based on detection of the oscillating magnetic flux due to the magnetization dynamics, with an inductive pickup loop. The dependence of the resonance frequency on applied static magnetic field agrees very well with the Kittel formula, demon...

Using the Landau-Lifshitz-Bloch (LLB) equation for ferromagnetic materials, we derive analytic expressions for temperature-dependent absorption spectra as probed by ferromagnetic resonance. By analyzing the resulting expressions, we can predict the variation of the resonance frequency and damping with temperature and coupling to the thermal bath. We base our calculations on the technologically ...

The dynamic magnetic properties of MgO/Fe epitaxial thin films are investigated through a network analyzer ferromagnetic resonance in the 0–26-GHz range. The high-frequency response is measured for applied in-plane magnetic fields comparable to the fourfold magnetocrystalline anisotropy of the film, resulting in large-angle in-plane quasistatic motion of the magnetization. We show that the vari...

In this paper, a magnetically tunable metamaterial is proposed and studied. The metamaterial is based on the combination of ferrite sheets and dielectric rods. The tunable property is originated from the ferromagnetic resonance and electric response of dielectric rods. The retrieved electromagnetic parameters and transmission characteristic showed that by simultaneously inspiring the ferromagne...

Ferromagnetic resonance modes in a single rectangular ${\mathrm{Ni}}_{80}{\mathrm{Fe}}_{20}$ microstrip were directly imaged using time-resolved scanning transmission x-ray microscopy combined with phase-locked ferromagnetic excitation scheme, and the findings corroborated by micromagnetic simulations. Although under uniform confined microstructure typically standing spin waves are expected, al...
