MOE-2 DiamagneticFaraday RotatorGlass: Diamagnetic materials generally offer lowerVerdet constant, hence lower measurement resolution, but they havebetter environmental stability, particularly temperature stabilitycomparing to paramagnetic Faraday Rotator elements. For thatreason, diamagnetic materials, especially diamagnetic glasses inbulk and fiber for, are commonly chosen as the sensing element inhigh stability Faraday effect sensor(Williams et al.,1991) Type 1: Verdet Constant: -0.071 min/Oe*cm or 20.64rad/T*m at 632.8 nmType 2: Verdet Constant: -0.093 min/Oe*cm or 27.1 rad/T*m at632.8nm
Indexof Refractive Nd(589.3nm): 1.9180
Dispersive index: 21.52
The Verdet constant of a diamagnetic medium depends only upon the dispersion curve of the medium and is not affected appreciably by mechanical or temperature effects. Diamagnetic Faraday Rotator Element is widely used in Magneto Optic Current Transformer(MOCT) and many other instruments.
