报告介绍 | 报告摘要:
Currently nano-structured metallic ferromagnetic thin films attract a lot of attention because of possible applications in microwave signal processing, generation of microwave signals, magnetic memory, magnetic logic and sensing.
These structures support propagation of slow magnetic polaritons: magnetostatic spin waves (MSW). MSW exist at microwave frequencies, their dispersion is magnetic field tuneable, and their wavelengths can be smaller than optical wavelength for the visible light. Furthermore, spin waves in magnetic materials are intrinsically highly nonlinear.
In my talk I will present some results of our experimental and theoretical studies of travelling and standing spin waves both on the millimetre scale and in nanostructured ferromagnetic films. Our experimental demonstrations of functionalities of these materials as wave-based logic gates and sensors of various substances will be also discussed.a |
