High Field Magnetooptics of Diluted Magnetic Semiconductors(Magnetooptics)

High Field Magnetooptics of Diluted Magnetic Semiconductors(Magnetooptics)
application/pdf Absorption and luminescence spectra of Cd_Mn_xSe (x=0.10 and 0.38) and reflectance spectra of Cd_Co_xSe (x=0.012) were investigated in high magnetic fields up to 25 T by a hybrid magnet and a magnetospectrometer with an optical fiber system.

Magnetooptics in Lanthanides

, 2003
In the visible-light region magneto optical Kerr measurements are affected by the thermal contraction of the crystal lattice. In lanthanides the magnetization-induced contraction (magnetostriction) is of the same order as the thermal contraction.

Magnetooptic bounce-cavity modulator

Applied Optics, 1979
In this paper a new type of magnetooptic modulator having a bounce-cavity structure is described. Direct amplitude modulation is achieved by utilizing the Faraday effect in conjunction with the differential reflectivity of dielectric mirrors for polarizations parallel to (TM) or perpendicular to (TE) the plane of incidence.

Dispersive magnetooptic filters

Applied Optics, 1982
The anomalous dispersion of the Faraday rotation near optical resonance lines can be employed to build extremely narrowband filters (0.01 A) with a very wide field of view (+/-45 degrees ). This paper investigates the properties of these filters.

Digital magnetooptic disk drive

Applied Optics, 1984
A magnetooptical disk drive employing some useful techniques for high performance has been developed for digital file use. A quadrilayer structure with AlN films promises high reliability of the medium as well as enhancement of Kerr rotation. The azimuth of the polarization plane is also increased by the beam splitter, of which Rs (reflectivity of S ...

Magnetooptical current transformer 3: Measurements

Applied Optics, 1980
A laboratory setup of a magnetooptical current transformer was established. A ingle-mode fiber acts as both a measuring sensor and a transmission line. The overall measurement accuracy at room temperature within a primary current range 50-1200 A is better than 0.24%, the SNR at 1000 A is 85 dB.
