Transparent, superparamagnetic KxICoyII[FeIII (CN)6] - Silica nanocomposites with tunable photomagnetism

Abstract

Moldable magnetism: Tunable photomagnetism is exhibited by homogeneous, optically transparent, moldable silica xerogel nanocomposites containing the ferromagnetic Prussian blue analogue KxCoyII[FeIII (CN)6]z. These materials also show a blue-shifted intervalence charge-transfer band and superparamagnetic behavior. The picture shows the temperature dependence of the field-cooled (FC) and zero-field-cooled (ZFC) dc magnetization μ of a xerogel sample (inset).
