Магнитооптические свойства атмосферного воздуха описывают взаимодействие молекул воздуха как с магнитными полями, так и со светом. Изучение этих свойств имеет важное значение для понимания динамики атмосферы, совершенствования дистанционного зондирования для мониторинга окружающей среды, разработки новых материалов для датчиков и оптических устройств, совершенствования методов медицинской визуализации, таких как магнитно-резонансная томография, и для продвижения фундаментальных научных знаний с возможным практическим применением. В работе исследованы магнитооптические свойства воздуха экспериментальными методами в слабых магнитных полях от 0,122 до 0,986 Тл. Изучены изменения коэффициента пропускания в видимом спектре при разной интенсивности магнитного поля. Полученные результаты показали уменьшение коэффициента пропускания с увеличением длины волны, что указывает на прямую корреляцию между коэффициентом пропускания и величиной магнитного поля. Отмечено снижение магнитооптических свойств, в частности коэффициента пропускания, при увеличении длины волны. Зафиксированы минимальные и максимальные значения коэффициента пропускания при длинах волн 460 нм и 665 нм соответственно. Замечено, что отношение интенсивностей, связанное со сдвигом спектров комбинационного рассеяния света, уменьшается с увеличением его смещения. При этом более высокие отношения интенсивностей наблюдаются в присутствии магнитного поля по сравнению с немагнитными условиями. Магнитооптический отклик имеет тенденцию смещаться в сторону больших длин волн с увеличением напряженности магнитного поля.

The magneto-optical properties of atmospheric air molecules describe how air molecules interact with both magnetic fields and light. Studying these properties is crucial for understanding atmospheric dynamics, enhancing remote sensing for environmental monitoring, developing new materials for sensors and optical devices, refining medical imaging techniques like Magnetic Resonance Imaging, and advancing fundamental scientific knowledge with potential practical applications. The objective of this study is to investigate the magnetic optical properties of air within a weak magnetic field ranging from 0.122 T to 0.986 T using experimental methods. The analysis focuses on the variations in transmittance across the visible spectrum with changes in magnetic field intensity. Results indicate a decrease in transmittance with increasing wavelength, demonstrating a direct correlation between transmittance and magnetic field strength. The magneto-optical properties, specifically transmittance, exhibit a decreasing trend with increasing wavelength, with minimum and maximum transmittance values recorded at 460 nm and 664.755 nm, respectively. Additionally, the transmittance of air spectrum is directly influenced by the applied magnetic field. Moreover, the intensity ratio associated with Raman spectra shift decreases with increasing Raman spectra shift, with higher intensity ratios observed in the presence of a magnetic field compared to non-magnetic conditions. Furthermore, the magnetooptical response tends to shift towards higher wavelengths with increasing magnetic field strength.
