A major obstacle in nanophotonic technology is the development of fast-switching magneto-optical nanomaterials. Due to challenges in translating traditional bulk magneto-optical materials’ properties to the nanoscale, the development of everything from telecommunications to spintronics is hindered until better nanomaterials are created. The field of magneto-nanoplasmonics has emerged in response. Though nanometal systems have been well-studied, the ceiling for improvement has been reached leading to the issue that the maximum magneto-optical enhancement is still insufficient for applications beyond sensing. Plasmonic nanocrystals can meet the challenge by taking advantage of the strong light matter interactions associated with the infrared localized surface plasmon resonance (LSPR), a phenomenon in which free electrons oscillate upon interaction with light. The potential to exploit this phenomenon has made plasmonic nanocrystals prime candidates for magneto-optical enhancement. Plasmonic semiconducting nanocrystals (PSNCs) have been shown to be competitive magneto-optical materials even against metallic system architectures. The poster evaluates n-type Cd2SnO4 (CTO), an understudied inverse spinel PSNC, through NMR and Optical methods to probe the relationship between the plasmon and magneto-plasmonic quality factors (Qopt and QMP).
