Preparation and magnetic properties of CoWO4 nanocrystals
Cobalt tungstate (CoWO4) nanocrystals with an average size of 20–50 nm were synthesized via a template- or surfactant-free hydrothermal route. The crystal structure and morphology of the as-synthesized CoWO4 sample were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Magnetic measurements on the as-synthesized CoWO4 nanocrystals indicate a Néel temperature (TN) of ?40 K. This lower TN may be a result of the nanostructured particles that reduce the exchange coupling. The new synthetic route presented in this paper has potential applications to fabricate other metal tungstates (MWO4) materials.

Abstract

Cobalt tungstate (CoWO4) nanocrystals with an average size of 20–50 nm were synthesized via a template- or surfactant-free hydrothermal route. The crystal structure and morphology of the as-synthesized CoWO4 sample were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Magnetic measurements on the as-synthesized CoWO4 nanocrystals indicate a Néel temperature (TN) of ?40 K. This lower TN may be a result of the nanostructured particles that reduce the exchange coupling. The new synthetic route presented in this paper has potential applications to fabricate other metal tungstates (MWO4) materials.
