By applying ultra-fast heating routines via spark plasma sintering (SPS) to supercrystalline pellets, materials with an enhanced combination of elastic modulus, hardness and saturation magnetization are achieved. Supercrystallinity-namely the arrangement of the constituent nanoparticles into periodic structures-is achieved through self-assembly of the organically-functionalized iron oxide nanoparticles. The optimization of the following SPS regime allows the control of organics' removal, necking, iron oxide phase transformations and nano-grain size retention, and thus the fine-tuning of both mechanical properties and magnetic response, up until the production of bulk mm-size superparamagnetic materials.en2516-02302019831393150Royal Society of Chemistryhttps://creativecommons.org/licenses/by-nc/3.0/PhysikJournal Articleurn:nbn:de:gbv:830-882.05140410.15480/882.242710.1039/c9na00222g10.15480/882.2427Other
