Magnetic nanoparticles have shown great capability of sensing biological molecules in solution by correlating the magnetic susceptibility with the nanoparticle surface coatings. Here, we report on a new experimental approach of measuring magnetic nanoparticle relaxation. It uses a broadband ferromagnetic resonance setup specifically designed for samples in solution, enabling measurements of nanoparticles at variable frequencies up to 40 GHz. This design enables precise determination of the g…
