Abstract

Negatively charged nanocrystals of the magnetic coordination network CsNiCr(CN)₆ were prepared in water through a seed-mediated growth with a few atomic layers accuracy and final sizes tailored from 6 to 30 nm. A lower limit of the magnetic single-domain critical size was determined to be around 15 nm possessing a blocking temperature above 20 K.
