Elastic neutron scattering in Quantum Critical Antiferromagnet Cr0.963V0.037....

We have performed elastic neutron scattering studies of the quantum critical antiferromagnet Cr0.963V0.037. We have found
that unlike pure Cr, which orders at two incommensurate wavevectors, Cr0.963V0.037 orders at four incommensurate and one
commensurate wavevectors. We have found strong temperature dependent scattering at the commensurate and incommensurate
wavevectors below 250 K. Results indicate that the primary effect of V doping on Cr is the modification of the nesting conditions
of the Fermi surface and not the decreasing of the Neel temperature.
