Figure 5From: Synthesis route and three different core-shell impacts on magnetic characterization of gadolinium oxide-based nanoparticles as new contrast agents for molecular magnetic resonance imagingMagnetometry graphs for SPGO and Gd 2 O 3 - DEG . Graphs of (a) SPGO and (b) Gd2O3-DEG magnetization (emu/g) plotted as a function of applied field (Oe). VSM magnetometry shows paramagnetic behavior of SPGO. Also, magnetization curve with S shape (sigmoidal) of Gd2O3-DEG nanoparticle is shown in (b) is similar to superparamagnetic materials.Back to article page
