摘要：In this work, numerous antiferromagnetic (AFM) and weak ferromagnetic (WFM) iron oxides were fabricated and used as contrast agents in magnetic resonance imaging application. These non-superparamagnetic iron oxides exhibit r(2)/r(1) ratios in a range of 20-110, and hence making them potential for T-2 contrast enhancers. Most strikingly, a Langevin-function relationship was found between r(2)/r(1) ratios and the specific surface area (S) values, r(2)/r(1) similar to L-2 (S-1), which is quite unique for AFM and WFM iron oxides. This finding enables us to precisely tailor their r(2)/r(1) ratios simply by manipulating their specific surface area via controlling morphology and structure in preparation.
