Magneto-Optical properties of GaP single crystal
The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...
متن کاملMagneto-optical spaser.
We present an electrodynamical model of a quantum plasmonic device--the magneto-optical (MO) spaser. It is shown that a spherical gain nanoparticle coated with a metallic MO shell can operate as a spaser amplifying circularly polarized surface plasmons. The MO spaser may be used in design of an optical isolator in plasmonic transmission lines as well as in spaser spectrometry of chiral molecules.
متن کاملOptical and magneto-optical constants of MnPt3
Optically thick films of MnPt 3 were deposited on quartz using dc magnetron sputtering. The films were covered with an SiO x protective overcoat and annealed in vacuum at 850 °C for 1 h to form the crystalline L1 2 ͑Cu 3 Au͒ cubic structure. These films have a high degree of long-range order and are highly textured with the ͑111͒ axis along the film normal. Variable angle spectroscopic ellipsometry...
متن کاملNonlinear magneto-optical Bragg gratings.
In magneto-optical gratings the magnetic dipolar coupling superimposed on the electric dipolar one introduces nonreciprocity and spectral discrimination between circular polarization states, measured by a Zeeman-like splitting of the photonic Bragg resonances. In a nonlinear regime the degree of nonreciprocity is modified by the photoinduced interplay of these splittings and their Stark-like sh...
متن کاملMagneto-optical Kramers-Kronig analysis.
We describe a simple magneto-optical experiment and introduce a magneto-optical Kramers-Kronig analysis (MOKKA) that together allow extracting the complex dielectric function for left- and right-handed circular polarizations in a broad range of frequencies without actually generating circularly polarized light. The experiment consists of measuring reflectivity and Kerr rotation, or alternativel...
