Nano-structured magnetic metamaterial with enhanced nonlinear properties
Nano-structuring can significantly modify the properties of materials. We demonstrate that size-dependent modification of the spin-wave spectra in magnetic nano-particles can affect not only linear, but also nonlinear magnetic response. The discretization of the spectrum removes the frequency degeneracy between the main excitation mode of a nano-particle and the higher spin-wave modes, having t...
متن کاملMagnetic levitation of metamaterial bodies enhanced with magnetostatic surface resonances
We propose that macroscopic objects built from negative-permeability metamaterials may experience resonantly enhanced magnetic force in low-frequency magnetic fields. Resonant enhancement of the timeaveraged force originates from magnetostatic surface resonances (MSRs), which are analogous to the electrostatic resonances of negative-permittivity particles, well known as surface plasmon resonanc...
متن کاملChemico- thermal synthesis of nano-structured cobalt with distinct magnetic property
The synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. The product is characterized by ICP, XRD, FESEM , and TEM, indicating that the as- synthesized particles have an amorphous structure with 1.76 for Co/B ratio, an average size of 50 nm. The transformation of intermediate phases into single phase nano- cryst...
متن کاملA d.c. magnetic metamaterial.
Electromagnetic metamaterials are a class of materials that have been artificially structured on a subwavelength scale. They are currently the focus of a great deal of interest because they allow access to previously unrealizable properties such as a negative refractive index. Most metamaterial designs have so far been based on resonant elements, such as split rings, and research has concentrat...
