Synthesis and properties of Cd/sub 1-x/Mn/sub x/S diluted magnetic semiconductor nanoparticles

Cd/sub 1-x/Mn/sub x/S diluted magnetic semiconductor (DMS) nanoparticles of crystallite size ranging from 20 to 300 /spl Aring/ and x from 0 to 8.65 have been chemically synthesized by using aqueous solution precipitation. Subsequent characterization has been carried out by X-ray diffractometry and TEM measurements. Magnetic properties of DMS particles have been measured with a SQUID magnetometer. A transition from a para-magnetic to a spin-glass state at a critical temperature T/sub f/ has been observed. The applied magnetic field dependence of T/sub f/ has also been measured.<
