Abstract. We have studied experimentally the Faraday effect in TlInS2 crystals. The Verdet constant VF  and the effective Faraday coefficient F'33  are determined at the light wavelength l=632.8nm under normal conditions. These parameters are equal to VF=(112.4±1.5)rad/(T×m) and F'33=0.9995F33+0.0005F11= (12.96±0.18)×10-13m/A, respectively. We have shown that, among magnetically non-ordered substances, TlInS2 represents an efficient magnetooptic material.

Анотація. Експериментально досліджено ефект Фарадея в кристалах TlInS2. Для довжини хвилі оптичного випромінювання l=632.8нм і за нормальних умов визначено сталу Верде і ефективну компоненту тензора ефекту Фарадея. Вони дорівнюють відповідно VF=(112,4±1,5)рад/(Tл×м)   і F'33=0,9995F33+0,0005F11= (12,96±0.18)×10-13м/A  . Показано, що кристали TlInS2 є достатньо ефективними магнітооптичними матеріалами серед магнітно-невпорядкованих середовищ.
