WebFor many years, Permalloy (Ni 81Fe 19) has been the material of choice for investigations of patterned magnetic elements, as it possesses negligible magneto-crystalline anisotropy … WebFrom the uniform FMR mode, we extract the saturation magnetization (M S ), damping (α ), and inhomogeneous broadening (Δ H 0) ; from the first perpendicular standing spin-wave (PSSW) mode, we extract the exchange stiffness (A ). M S and A are found to decrease with increasing alloying, most strongly for Au and less so for Pt.

WebSedangkan untuk modifikasi exchange stiffness constant, ada anomali atau keanehan yang terjadi ketika nilai konstanta yang diberikan sebesar 1×10^(-6) erg/cm. Jika sudah melewati nilai tersebut, medan eksternal yang dibutuhkan untuk reversal mengalami kenaikan sebanding dengan nilai exchange stiffness constant yang digunakan. Web8. feb 2024 · Here, we focus on a FMR technique that relies on the observation of higher order spin wave resonances dominated by the exchange stiffness constant, which manifests in the direction perpendicular to the plane of the film due to constraints of film thickness, known as perpendicular standing spin waves (PSSWs). 26 26.
