The technique of photo-acoustic detection has successfully been applied to the observation of spin wave resonance in thin ferromagnetic films for the first time. Absorption spectra at room and liquid nitrogen temperatures are presented and values for the exchange stiffness constant D are evaluated for...

Here we report the direct measurements of an inequality between the spectral directional emissivity and absorptivity for a photonic design that supports a guided-mode resonance coupled to a magneto-optic material. This inequality occurs under the application of an in-plane magnetic field that modifies...
T1 is the longitudinal spin relaxation, which accounts for the persistence of the spin magnetic component parallel to the magnetic field, when the magnetization is perturbed from the equilibrium value. From: Methods in Enzymology, 2022 About this pageSet alert ...
2f. When approaching the Γ point from the M point, the degree of spin polarization decreases and it becomes negligible at the Γ point. On the other side of the Γ point, the spin polarization is reversed. The observation of spin polarization along the in-plane tangential direction with ...

Meanwhile, Lu et al.[158]found that spin transfer in Pt/YIG bilayer system can control the relaxation ofspin resonance, which is consistence in principle with the observedspin waveamplification, since the damping is countered by the thermally induced spin transfer torque. ...
Spin decoupling, which is a type of multiple irradiation, is an artificial way of reversing this condition so that the coupling between nuclei is removed. This is achieved by strongly irradiating a nucleus at its resonance frequency while observing another to which it is coupled. The effect of ...
