Abstract

The Néel temperature TN(n) of the Co3O4 antiferromagnet nanostructured in channels of porous borosilicate glass with channel cross sections of ∼7 nm has been determined from thermal conductivity measurements. It has been shown that the Néel temperature TN(n) of this nanomaterial is approximately equal to 20 K, which is considerably lower than TN = (30–40) K for the bulk Co3O4 sample.
