Layer-sensitive magneto-optical spectroscopic study of magnetization dynamics in multilayered RE-TM structures

Calculation of Magneto-optical Spectra in Compositionally-modulated Multilayered Films

Magneto-optical spectrum of compositionally modulated multilayered thin films (CMF) of transition metal/noble metal structure is calculated by using virtual optical constant method, by which most of the experimental results are explained. The physical reasons of enhancement of magneto-optical effect are discussed. Compositionally-modulated multilayered films (CMF) are of recent interest among r...

Magneto-optical Effects in Transparent Media under Inhomogeneous Magnetization

The analysis of the Magneto-Optical (M. 0.) effects when the magnetization is inhomogeneous is separated in two cases : first, when no diffraction occurs inside the medium, the geometrical optics approximation is used to derive the phase of the optical fields and the ray paths. Second, with no negligible diffraction inside themedium, extensions of the previous theory are presented and applied t...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...

Development of a Near-Field Magneto-Optical Microscopy for Studying Ultrafast Magnetization Dynamics

Apertureless magneto-optical near-field microscopy is developed for studying subpicosecond spindynamics at nanometer spatial scale. Polarization modulation and tip vibrations are implemented. Polarization responsivity of the tip-induced scattering is demonstrated using polarization modulation and tip vibrations. A near-field magneto-optical contrast is achieved for a thin ferromagnetic film wit...
