Abstract
The potential use of the Faraday effect for a fiber-optic magnetic sensor has already been proposed.1,2 Typical magnetooptical materials are YIG and heavy flint glass. These materials, however, have intrinsic disadvantages: large Verdet constant temperature dependence for YIG (+16%, 300 → 400 K) and small Verdet constant for heavy flint glass (1.6 × 10−3 deg cm−1 Oe−1) compared with YIG (2.1 × 10−1deg cm−1 Oe−1).
