Abstract
dc:description.abstractMagnetic semiconductor nanocrystals are being studied for their potential application in the field of spintronics as spin-injectors for spin-based transistors and spin-based storage elements for nonvolatile memories. They also have a number of biomedical engineering applications including contrast enhancing agents for magnetic resonance imaging (MRI). In this study, we present a synthesis route to grow colloidal II-VI magnetic nanoparticles at room temperature with easily handled, relatively non-toxic source materials. CoSe and CrSe nanocrystals were synthesized in an aqueous solution where gelatin is used to retard the reaction. Characterization of the nanocrystals was done through transmission electron microscope (TEM) imaging and UV-Vis absorption spectroscopy. Spin-carrier relaxation times were determined using a superconducting quantum interference device (SQUID) magnetometer.
