Electromagnetic Effects of Spin Wave Resonance in Ferromagnetic Metals

Abstract

cm -', this being the value of kp corresponding to a Fermi energy of 4 ev. Because the dependence of R on g is given roughly by R~q 4, the uncertainty in the choice of q does lead to considerable uncertainty in R.Comparison of the theoretical and empirical values of q for sodium enables one to say that, for sodium at least, our estimate of R is not in error by more than a factor of 5.By an approximate integration of (1) it is easily

Detection of microwave phase variation in nanometre-scale magnetic heterostructures

“…The physical content of the simulations consists solely of Maxwell's equations for the conductors and the LLG equation for the ferromagnets, as outlined in classic work by Ament and Rado 25 . The layer-specific magnetization response is interpreted as a local measurement of complex, thickness-averaged magnetic fieldsH in the layers.…”

“…The Rado-Ament analysis 25 requires that the fields in the conductive ferromagnet satisfy both microwave screening through the susceptibility-reduced skin depth,…”

Microwave response and spin waves in superconducting ferromagnets

“…This property has been widely used in ferromagnetic resonance measurements in metals. 12,15 Thus, superconductivity modifies the microwave response in a qualitative way, which can be used for detection of the superconducting transition.…”

Спин-волновой резонанс в химически осажденных Fe-Ni пленках: измерения спин-волновой жесткости и константы поверхностной анизотропии

“…Определяющим условием регистрации спектра СВР в магнитной пленке является закрепление магнитно-го момента на ее поверхностях [14,15], количествен-ная оценка степени закрепления определяется вели-чиной (и знаком) константы поверхностной анизотро-пии K S . Последнее позволяет в некоторых случаях из спектров СВР проводить прямые измерения величи-ны K S .…”
