The N,el temperature T (N(n)) of the Co3O4 antiferromagnet nanostructured in channels of porous borosilicate glass with channel cross sections of similar to 7 nm has been determined from thermal conductivity measurements. It has been shown that the N,el 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.
