Spin fluctuations in the antiferromagnetic heavy-fermion system U/sub 2/Zn/sub 17/

· Phys. Rev. Lett.; (United States)
Inelastic neutron scattering from the antiferromagnetic (T/sub N/ = 9.7 K) heavy-fermion system U/sub 2/Zn/sub 17/ reveals magnetic fluctuations which are highly localized in reciprocal space and broad in frequency. At higher energies, the fluctuations persist almost unchanged to temperatures well above T/sub n/. Analysis of the neutron and bulk susceptibility data in terms of Kondo-type single-ion response functions modified by Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions between ions indicates that it is the temperature dependence: anticipated theoretically: of the effective RKKY coupling which drives the magnetic phase transition in U/sub 2/Zn/sub 17/.
