Abstract

Here we explore the potential of ferromagnetic resonance (FMR) spectroscopy, using the Landau–Lifshitz–Gilbert (LLG) equation, by identifying and characterizing coexisting conductive and insulating magnetic phases within lanthanum-doped yttrium iron garnet (YIG) nanoparticles. The samples were synthesized via sol–gel method and calcined. Single-phase YIG formation and secondary orthorhombic YFeO

考虑绝缘掺la YIG和导电YFeO3相的FMR信号分析

在这里，我们利用Landau-Lifshitz-Gilbert （LLG）方程，通过识别和表征掺镧钇铁garnet （YIG）纳米颗粒中共存的导电和绝缘磁相，探索了铁磁共振（FMR）光谱的潜力。采用溶胶-凝胶法制备了样品，并进行了煅烧。通过x射线衍射（XRD）分析，发现YFeO3形成了单相yfeg和次生正交相。FMR测量结果显示yg和YFeO3具有明显的磁特征。
