We show that very diluted dispersions of ferromagnetic metal nanoparticles in diamagnetic hosts show a large, linear response under an applied magnetic field, which is of interest for emerging applications in sensing, integrated optical communications, and magneto-optical current transformers and transducers. We present also a theory that describes accurately these results and that can be further extended to describe the optical properties of e.g., metal inclusions in polymers or glasses.
