Abstract

Cd1-xMnxS diluted magnetic semiconductor ultrafine particles with sizes in the range 20 to ≃ 1200 Å and 0 ≤ × ≤ 0.5 have been synthesized by using aqueous solution precipitation. We find that size has a significant effect on the magnetic spin-glass (SG) properties of these systems. The SG freezing temperature Tf decreases with size, and there is a minimum size below which the SG does not form. The field dependence of Tf and the relaxation of the isothermal remanent magnetization are also significantly different than in the bulk.
