Abstract: Plasmonic NPs have a variety of applications in electronics, optoelectronics, biomedics and medicine but, NPs such as gold and silver are very costly. We can explore the same plasmonics properties by adding other materials into it. In recent years, the latest trend is to use magnetic field with plasmonic properties. To achieve the enhancement in optical properties with magnetic nature, the study appeals the combination of noble metals with magnetic (ferromagnetic) materials which leads to highly appealing nanostructures with increased functionalities. This new field emerging by the combination of magnetic and plasmonic NPs is called magneto-plasmonics. The use of complex structures made from ferromagnetic (Fe, Co and Ni) materials and noble metals (Au and Ag) have been proposed. The main aim is to use the magnetism and plasmonic together to enhance the optical properties. From the literature survey it is very clear that a sporadic research findings both theoretical and experimental in the field of magnetoplasmonics have been reported by the researchers but still there are various gaps about the tunability of optical properties of magneoplasmonic nanostructures with their parameters like materials, shapes, size, etc. which are unrevealed yet and need systematic investigations in order to make most out of these magnetoplasmonic nanostructures in different applications.
