1) Verdet constant 维尔德常数1. Experimental results show that the Verdet constant changes with the variation of terbium ions concentration, when the Faraday rotation glass contains 20% (mol) of Tb2O3 the Verdet constant is-0. 本文研究了掺Tb_2O_3的法拉第旋转玻璃的组成、物理化学性质及制备...
Details are presented of Faraday rotation measurements on holmium doped soda glasses. A very large change in the Verdet constant has been observed near to 450nm which may have practical application. The observations represent the first published data of resonance Faraday rotation in a glass matrix....
The effects of the central wavelength shift of the source and the variations of the parameters of the sensing head (Verdet constantand linear birefringence) due to ambient temperature fluctuation upon the scale factor of a bulk-glass optical current transformer are theoretically analyzed and digitally...
Faraday effect measurement has been carried out for 30TbO·70BOglass at room temperature. The magnitude of the Verdet constant is 0.838 min/cm·Oe at the wavelength of 450 nm. This value is large compared with those reported for other glasses containing trivalent rare-earth ions. The wavelength...
nanoparticle and a plurality of organic polymer ligands attached to its surface. The composition can also include a host matrix, such as a polymer, in which the magnetic nanocomposite particles are interspersed therein. The compositions of the invention have the Verdet constant of at least 5000°/...
The verdet constant of the magnetic optic glass reaches -0.425min/Oe.cm (632.8nm), and is far higher than that of international general terbium glass.殷海荣汪涛胡宝云董继先
The quantum dot doped phosphate glass gave Verdet constant of 5.17 °/T-cm for 1% doping concentration which was approximately 17 times more than the Verdet constant of the plain phosphate glass.Tennessee Technological University.Kumar, Ganapathy....
This temperature dependence can be entirely attributed to the change in the Verdet constant of the glass. This is, to our knowledge, the first report of a birefringence free fiber-optic current sensor with Verdet constant limited performance. The sensor's response to current is linear to within...
