A rigorous twodimensional model for the stripline ferromagnetic resonance response of metallic ferromagnetic films
Abstract
In this work, we constructed a twodimensional numerical model for calculation of the stripline ferromagnetic resonance (FMR) response of metallic ferromagnetic films. We also conducted numerical calculations by using this software. The calculations demonstrated that the eddy current contribution to the FMR response decreases with a decrease in the stripline width. The most important manifestations of the conductivity (eddy current) effect are excitation of the higherorder standing spin waves across the film thickness in the materials for which the standing spin wave peaks would be absent in cavity FMR measurements and strong dependence of the offresonance series conductance of the stripline on the stripline width. Whereas the contribution of the eddy currents to the stripline FMR response can be very significant, because wide striplines (100 μm+) are conventionally used for the FMR measurements, it is negligible in the case of excitation of spin waves, just because very narrow stripline transducers (0.5–5 μm wide) are required in order to excite spin waves in metallic ferromagnetic films in a noticeable frequency/applied field range.

We constructed a quasianalytical selfconsistent model of the striplinebased broadband ferromagnetic resonance (FMR) measurements of ferromagnetic films. Exchangefree description of magnetization dynamics in the films allowed us to obtain simple analytical expressions. They enable quick and efficient numerical simulations of the dynamics. With this model, we studied the contribution of radiation losses to the ferromagnetic resonance linewidth, as measured with the stripline FMR. We found that for films with large conductivity of metals the radiation losses are significantly smaller than for magnetoinsulating films. Excitation of microwave eddy currents in these materials contributes to the total microwave impedance of the system.more »

Ferromagnetic resonance linewidth in metallic thin films: Comparison of measurement methods
Stripline (SL), vector network analyzer (VNA), and pulsed inductive microwave magnetometer (PIMM) techniques were used to measure the ferromagnetic resonance (FMR) linewidth for a series of Permalloy films with thicknesses of 50 and 100 nm. The SLFMR measurements were made for fixed frequencies from 1.5 to 5.5 GHz. The VNAFMR and PIMM measurements were made for fixed inplane fields from 1.6 to 8 kA/m (20100 Oe). The results provide a confirmation, lacking until now, that the linewidths measured by these three methods are consistent and compatible. In the field format, the linewidths are a linear function of frequency, with amore » 
Spinscattering rates in metallic thin films measured by ferromagnetic resonance damping enhanced by spinpumping
We determined the spintransport properties of Pd and Pt thin films by measuring the increase in ferromagnetic resonance damping due to spinpumping in ferromagnetic (FM)nonferromagnetic metal (NM) multilayers with varying NM thicknesses. The increase in damping with NM thickness depends strongly on both the spin and chargetransport properties of the NM, as modeled by diffusion equations that include both momentum and spinscattering parameters. We use the analytical solution to the spindiffusion equations to obtain spindiffusion lengths for Pt and Pd. By measuring the dependence of conductivity on NM thickness, we correlate the charge and spintransport parameters, and validate the applicabilitymore » 
Rigorous bounds of the Lyapunov exponents of the onedimensional random Ising model
We find analytic upper and lower bounds of the Lyapunov exponents of the product of random matrices related to the onedimensional disordered Ising model, using a deterministic map which transforms the original system into a new one with smaller average couplings and magnetic fields. The iteration of the map gives bounds which estimate the Lyapunov exponents with increasing accuracy. We prove, in fact, that both the upper and the lower bounds converge to the Lyapunov exponents in the limit of infinite iterations of the map. A formal expression of the Lyapunov exponents is thus obtained in terms of the limitmore »
