Diffractive magneto-optics, magnetic interactions, and reversal mechanisms in Co microsquare arrays
The magneto-optical properties of Co microsquare—2 mm edge—arrays have been investigated for different interelement separations, from 0.2 to 2.0 mm. The magneto-optical response is measured both at reflected and diffracted beams, and it is compared with the results of a model that uses micromagnetic simulations and optical diffraction theory to calculate the magneto-optical response for differe...
متن کاملSuperconductor Magneto-optics and Theory
Some remarks are made on how to determine by magneto-optical imaging the electric currents flowing in a superconductor. The inversion problem is discussed how to compute these currents from the magnetic field measured in a planar magneto-optical indicator film positioned close to the conductor. Next, some geometries are listed for which the currents and magnetic fields can be computed from firs...
متن کاملFemtosecond spectrotemporal magneto-optics.
A new method to measure and analyze the time and spectrally resolved polarimetric response of magnetic materials is presented. It allows us to study the ultrafast magnetization dynamics of a CoPt3 ferromagnetic film. The analysis of the pump-induced rotation and ellipticity detected by a broad spectrum probe beam shows that magneto-optical signals predominantly reflect the spin dynamics in ferr...
متن کاملDiffracted evanescent wave model for enhanced and suppressed optical transmission through subwavelength hole arrays.
Transmission enhancements of order 1000 have been reported for subwavelength hole arrays in metal films and attributed to surface plasmon (SP) resonance. We show that the properly normalized enhancement factor is consistently less than 7, and that similar enhancements occur in nonmetallic systems that do not support SPs. We present a new model in which the transmission is modulated not by coupl...
