Abstract
Abstract. This article
discusses the properties of different diamagnetic and paramagnetic materials
for a basic current/magnetic field sensor system set up with different
relative orientations of analyzers and polarizers. The paper analyzes
linearity ranges of different materials and their sensitivity for different
wavelengths. Terbium doped glass (TDG), terbium gallium garnet (TGG), doped
TGG and dense flint glass materials are used for analysis based on Faraday's
rotation principle. TGG shows high Faraday rotation, temperature stability
and high optical quality. Three ranges of the magnetic field have been chosen
for performance analysis. The study reveals that doping of praseodymium
(Pr3+) on TGG exhibits a better response at 532 nm as well as
1064 nm wavelengths than TGG. At 632.8 nm wavelength, cerium
(Ce3+) doped terbium aluminum garnet (TAG) ceramic exhibits better
resolution than others. The study has been done for performance analysis of
different MO sensors applicable for measurement of various process parameters
like current, displacement, and magnetic field.
