Abstract
The Néel temperature T N(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 T N(n) of this nanomaterial is approximately equal to 20 K, which is considerably lower than T N = (30–40) K for the bulk Co3O4 sample.
