I am currently working on Surface Plasmon Resonance-based PCF sensors. I want to utilize my sensor as a magnetism sensor. Therefore I need to utilize magnetism-sensitive fluids as an analyte of my sensor. However, I could not find any specific equation that relates the RI (refractive index) of a fluid with the applied magnetic field. Could anyone help me in this regard?
Dear Md Moinul Islam Khan ,
up to now I was only aware on the magneto-optical effect in solids;
but please google for 'magneto optical effect in fluids'.
You will see that a lot of informations will pop up with respect to ferro-fluids, e.g. based on nanoparticles.
Please have for example a look on:
Article High-sensitivity vector magnetic field sensor based on side-...
Chapter Magneto-Optical Tuning of Refractive Index for Bidispersed Ferrofluid
Article Tunable refractive index of magnetic fluids and its applications
Please request for full-text(s) or get access to full-texts via your institution.
Good luck
