Abstract. We have studied experimentally the Faraday effect in Tl3AsS4 crystals. The effective Faraday tensor coefficient and the Verdet constant are determined under normal conditions and 632.8 nm . They are equal to 0.06F11+0.94F22=(9.23±0.21)10-13 m/A  and VF=(82.2±1.8)rad/Tm , respectively. We have shown that the Tl3AsS4 crystals are one of the most efficient magnetooptic materials among magnetically non-ordered ones.

Анотація. У цій роботі експериментально вивчено ефект Фарадея в кристалах Tl3AsS4 Визначено ефективний коефіцієнт Фарадея та сталу Верде за нормальних умов на довжині хвилі 632.8нм. Вони дорівнюють відповідно 0,06F11+0.94F22=(9,23±0,21)10-13 м/А і VF=(82,2±1.8)рад/Тлм. Показано, що кристали Tl3AsS4 можна віднести до найефективніших магніто-невпорядкованих матеріалів для магнітооптичних застосувань..
