Nanoparticles of diluted magnetic semiconductor Zn1-x Crx Te with various Cr concentrations were synthesized by a chemical method, and their magnetic properties were investigated. The synthesized nanoparticles show ferromagnetism, and the saturation magnetization increased with increasing Cr concentration in the range from x=0.002 to x=0.02. The Zn0.98 Cr0.02 Te nanoparticles showed ferromagnetism above room temperature, where the Curie temperature TC was estimated to be about 520 K. This is much higher than the reported value of TC in the Zn1-x Crx Te thin films.
