Abstract. We have studied experimentally the Faraday effect in AgGaGe3Se8 crystals. The Verdet constant VF and the effective Faraday coefficient F'11 are determined at the light wavelength l=632.8nm  under the normal conditions. They are equal to VF=(69.5±2.8)rad/(Tm) and F'11=0.96F11+0.04F33=(8.36±0.33)10-13m/A, respectively. We have shown that, among magnetically non-ordered substances, AgGaGe3Se8 represents an efficient magnetooptic material.

Анотація. Експериментально досліджено ефект Фарадея в кристалах AgGaGe3Se8. На довжині хвилі оптичного випромінювання l=632.8нм  і за нормальних умов визначено сталу Верде і ефективну компоненту тензора ефекту Фарадея. Вони дорівнюють VF=(69,5±2,8)рад/(Tлм)  і F'11=0,96F11+0,04F33=(8,36±0,33)10-13м/A , відповідно. Показано, що кристали AgGaGe3Se8 є досить ефективними магнітооптичними матеріалами поміж магнітно невпорядкованих середовищ.
