We investigated the magnetic susceptibility and thermal expansion of alloys of chromium with 1.4l atomic % of Co, chromium with 1.4l atomic % of Co plus 0.77 atomic % of V , and chromium with 0.34 atomic % of Fe plus 0.78, 1.08 and 1.63 atomic % of V over the 77 to 400°K temperature range. The fraction of magnetic susceptibility Δχ, due to addition of V , Fe and Co, is identified. Above the Neel temperature the behavior of Δχ(Т) obeys the Curie-Weiss law in all cases. Analysis of results shows that at low concentrations, atoms of V have a local magnetic moment ~ 1μ$_{{B}}$ in the Cr matrix.
