| Popis: | We review measurements of the high-frequency magnetic excitations in the paramagnetic alloy Cr0.95V0.05 made using pulsed spallation neutron techniques. Spatially coherent magnetic excitations are observed up the highest energy investigated, h ω = 400 meV . The wavevector-integrated or local susceptibility increases approximately linearly with frequency up to this energy. Our observations contrast strongly with those on pure Cr in its paramagnetic phase. |
