Surface plasmon resonance enhanced magneto-optics (SuPREMO): Faraday rotation enhancement in gold-coated iron oxide nanocrystals.
We report enhanced optical Faraday rotation in gold-coated maghemite (gamma-Fe(2)O(3)) nanoparticles. The Faraday rotation spectrum measured from 480-690 nm shows a peak at about 530 nm, not present in either uncoated maghemite nanoparticles or solid gold nanoparticles. This peak corresponds to an intrinsic electronic transition in the maghemite nanoparticles and is consistent with a near-field...
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 کاملExtreme Ultraviolet Stokesmeter for Pulsed Magneto-Optics
Several applications in material science and magnetic holography using extreme ultraviolet (EUV) radiation require the measurement of the degree and state of polarization. In this work, an instrument to measure simultaneously both parameters from EUV pulses is presented. The instrument determines the Stokes parameters after a reflection on an array of multilayer mirrors at the Brewster angle. T...
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 کاملMarine Optics: Dark Disguise
Survival in the deep sea depends on seeing others without being seen yourself. A recent study examined two switchable camouflage strategies in cephalopods: transparency and dark pigmentation.
