<description xml:lang='en' descriptionType='Abstract'><p>We study magnetic behavior of the Yb3+ ions on a frustrated pyrochlore lattice in the spinel CdYb2Se4. The crystal-electric-field parameters deduced from high-energy inelastic neutron scattering reveal a well-isolated ytterbium ground-state doublet with a weakly Ising character. Magnetic order studied by powder neutron diffraction evolves from the XY-type antiferromagnetic &Gamma;5 state to a splayed icelike ferromagnet (both with k=0) in applied magnetic field with Bc=3T. Low-energy inelastic neutron scattering identifies weakly dispersive magnetic bands around 0.72 meV starting at |Q|=1.1&Aring;-1 at zero field, which diminish with field and vanish above 3 T. We explain the observed magnetic behavior in framework of the nearest-neighbor anisotropic exchange model for effective S=12 Kramers doublets on the pyrochlore lattice. The estimated exchanges position the CdYb2Se4 spinel close to the phase boundary between the &Gamma;5 and splayed ferromagnet states, similar to the Yb pyrochlores, suggesting an important role of the competition between these phases.</p></description>
