“…Also, the dependence of transmitted light intensity on the field intensity was also studied extensively in the past several years. Results showed that beyond the critical field of certain value, the transmitted intensity firstly shows an increase trend while after the maximum it reduces with the field intensity [39][40][41][42]. However, it should be noted that the time effect was not considered for most field-dependent light transmission studies in the past.…”

In recent years, the magneto-optical properties of magnetic nanofluids have received increasing attention due to their wide range of applications in various solar energy conversion processes and also as smart fluids in tunable photonic device, optical switch, optical fiber sensor, etc. This article reviews up-to-date developments in magneto-optical transmission in ferrofluids for different optical applications. With magnetic field, the magnetic nanoparticle will undergo interesting structural transitions including chainlike formation and lateral coalescence, leading to various light transmission phenomena in ferrofluids. The orientation of the magnetic field relative to the incident light has a significant influence on the intensity of transmitted light through the suspensions. For incident light along the magnetic field, the polarization direction of light has a negligible effect on the magneto-optical transmission. However, the polarization direction of light should make a great difference for light normal to the field direction. These recent studies are comprehensively reviewed, and their main findings and potential applications are also presented and discussed. Our study is supposed to provide a general view on the research trends, existing problems and future work for the investigation of magneto-optical transmission in magnetic nanofluids.

Optical field enhancement maximization has been the ultimate objective of applications covering random lasers, spectroscopy, and ‐importantly‐ targeted drug delivery. Consequently, scientists resorted to plasmonic based approaches, which rendered the entire approach inapplicable due to biodegradability concerns. In another work, an experimental realization for a method of magneto‐optical transmission maximization is reported. However, possible limitations on the higher excitation power needed for biomedical applications are still questionable. Furthermore, a comprehensive, quantitative understanding of all material and design related parameters influencing this enhancement is still needed for complete control over possible applications. Therefore, successfully derives a model for the magneto‐optical transmission under a time‐varying 0–4 kHz magnetic field, exhaustively accounting for material and design related phenomena; birefringence of hematite, dissipation, randomness, and anisotropy on the dielectric function, scattering cross‐section, and polarizability, for the first time. The model achieves an accuracy of 99.99% over the band 300–1100 nm and exhausts the model limitations to the decay time constant of Cotton–Mouton co‐effects. The dynamics of the problem are also derived, accounting for the influence of the magnetic field on the viscosity of the ferrofluid, which leads to an in‐depth, required understanding of the magneto‐optic interactions with ferrofluids for efficient applicability.
