Abstract

A nanoparticle-type of cobalt hexacyanochromate, K_0.19^I Co^II [Cr^III (CN)₆]_0.73 · 4.5 H₂ O (particle diameter = 8 ± 2 nm) is prepared in Nafion. The nanoparticles show the superparamagnetism with blocking temperature (T_B) of 8.5 K and an anisotropy energy barrier of 190 K. Magnetic hysteresis loops are observed below T_B, e.g. 1.2 kOe at 2 K.
