The magnetic susceptibility of the itinerant antiferromagnet with is studied as a function of the hydrostatic pressure up to at fixed temperatures 78 and . The pressure effect on is found to be negative in sign and weakly dependent on the magnetic state of the compound. In addition, the measured pressure dependence of the Néel temperature, , is roughly two orders of magnitude smaller than the corresponding value for the pure chromium. The main contributions to and their volume dependence are calculated ab initio within the local spin density approximation, and they turn out to be in close agreement with the experimental data.
