(a) Experimental absorbance of Co-NPs in hexane. As grown Co-NPs (red), after 1 hour sonication with external 130 mT DC magnetic field (blue), after 2.5 hours sonication with external 130 mT DC magnetic field (green, plasmon peak is demolished), no magnetic field and 1 hour sonication (black). (b) Co-NPs size distribution measured with dynamic light scattering (red)- as grown; (green) −2.5 hours sonication with external 130 mT DC magnetic field; (black) after 1 hour sonication without magnetic field.
