MAGNETOTRANSMISSION EFFECT IN MAGNETOSTRICTIVE CoFe2O4 FOR THE CASE OF THE VOIGT GEOMETRY
DOI: 10.17804/2410-9908.2018.6.149-156 Infrared absorption spectra are obtained for a ferrimagnetic single crystal of ferrite CoFe2O4. It is shown that an external magnetic field applied in the Voigt geometry leads to a noticeable change in the transparency of the single crystal possessing high magnetostriction – the magnetotransmission effect (up to 10% in a 2 kOe field). The direct correlation between magnetotransmission and magnetostriction in the ferrite was established at room temperature. The anisotropy of the magnetotransmission of natural infrared radiation in CoFe2O4 is studied for the first time.

МАГНИТОПРОПУСКАНИЕ В МАГНИТОСТРИКЦИОННОМ КРИСТАЛЛЕ CoFe2O4 В ГЕОМЕТРИИ ФОХТА
Получены спектры поглощения для ферримагнитного монокристалла феррита CoFe2O4 в инфракрасном диапазоне спектра. Показано, что внешнее магнитное поле в фохтовской геометрии эксперимента приводит к заметному изменению прозрачности магнитострикционного монокристалла в широкой ИК-спектральной области – эффекту магнитопропускания света (до ~10 % в поле 2 кЭ). Установлена корреляция между магнитопропусканием и магнитострикцией феррита при комнатной температуре. Впервые изучена анизотропия магнитопропускания ИК-излучения в монокристалле CoFe2O4.
