The precession of the spin results in the time-dependent mechanical torque acting on the nanoparticle. The parameter-free nature of the torque can be traced to the conservation of the total angular momentum (spin + mechanical). The resulting mechanical vibration of the particle on the surface of the solid generates acoustic waves.

Dec 04, 2019 · 15.2 Homomorphism of Uniform Plane Waves and Transmission Lines Equations. 148 1These polarizations are also variously know as the sand ppolarizations, a descendent from the notations for acoustic waves where sand pstand for shear and pressure waves respectively. When a magnetic system is excited by a high-frequency EMW, the excited spin system responds with a spin-wave (SW) excitation spectrum, strongly depending on the shape and size of the particles. In nanosize particles of nonellipsoidal geometry, the SW spectra are peculiar, as it is described in Section 21.3.1.

Aug 29, 2017 · There are many articles that extensively deal with the classification of methods of nanoparticles synthesis [28,43,44,69,70,71,72,73,74,75,76] even on an ultra-large-scale or more usually in terms of synthesis and surface functionalization of particular types of magnetic nanoparticles, e.g., magnetic iron oxide nanoparticles [39,40,73,78,79,80. Abstract Inelastic neutron scattering is utilized to measure the spin waves, or magnons, which arise from inter-particle coupling between 8.4 nm ferrite nanoparticles that are self-assembled into a close-packed lattice, yet physically separated by oleic acid surfactant. Numerical modeling of spin configurations in these nanoparticles yields 8, 6, or 4-sublattice configurations, indicating a finite size effect, in which the reduced coordination of surface spins causes a change in the magnetic order throughout the particle [16], [8].
