Abstract
PURPOSE: To eliminate the temperature dependency of the Verdet constant itself and enable the stable operation within a wide temperature range by using the materials having the temperature coefficient of positive and negative magneto-optic effects through alloying or bonding.
CONSTITUTION: For example, at the time of connecting and arraying the materials A and B having the positive and negative temperature coefficients in the Faraday rotating angle under magnetic field by temperature change ΔT in the lengthwise direction, they are made to the lengths lA, lB inversely proportional to the temperature coefficients αA, αB of the materials A, B. Namely if the ratio of the element lengths are made lA/lB=-αB/αA, the element having no temperature dependency may be provided.
