Magnetic nanoparticle (MNP) thermometry is a promising approach for non-invasive and remote temperature sensing for applications in both fundamental and applied sciences. However, the small thermosensitivity (temperature-dependent magnetization) of conventional single magnetic material MNPs (e.g. magnetite or other ferrites) limit the requisite sensitivity needed for practical applications. Bimagnetic nanoparticles with tunable thermosensitivity and operating temperature ranges represent a potential route to overcome these limitations. Here we present results on the temperature-dependent AC magnetization of synthesized cobalt-doped ferrite MNPs and demonstrate the feasibility of engineered material composition and structure towards the realization of a highly sensitive MNP thermometer.
