Valeri Lozovski (Taras Shevchenko National University Kiev): The self-consistent description of plasmon-assisted Brillouin Light Scattering (BLS) spectroscopy

Research Project

Optical studies of magnetic systems are non-destructive, provides high sensitivity and thus, are perspectives. The methods based on the scanning optical microscopy can provide the high space resolution. An important feature of magnetic-optical studies is that they do not require magnetic probes and thus do not affect the magnetic structure of the studied systems. The most important is that optical studies  can be carried out in external magnetic fields.Brillouin light scattering (BLS) is well established a very powerful tool to investigate the magnetization dynamicsin different ferromagnetic nanostructures. To enhance the Brillouin scattering of light intensity and obtain acceptable resolution we propose to use the elements of technique of apertureless scanning near-field optical microscopy (a-SNOM) and local-field enhancing effect in nano-plasmonic systems. Using the apertureless probe scanning along the surface with nanoplasmonic structure, one canachieve a high resolution when the reflected field being measured. 

Thus, the aim of the Project is developing the theoretical base for the proposed method.
