Description
The Kondo lattice antiferromagnet YbNiSi3 was investigated by neutron scattering techniques. The magnetic structure of YbNiSi3 was determined by neutron diffraction techniques on a single-crystalline sample. We revealed that the magnetic moments of Yb atoms align along the b-axis and are composed a ferromagnetic bc plane stacking antiferromagnetically along the a-axis. Inelastic neutron scattering experiments were also performed on a pulverized sample to study the crystalline electric field (CEF) excitations. Two broad CEF excitations were observed, from which we propose a plausible CEF model. The temperature dependences of the magnetic susceptibility χ and the magnetic specific heat Cmag were calculated using the probable CEF parameters, and compared with previous results. (author)
